[Nate the Great]

PICARD: Counsellor, do you remember when I first came on board the Enterprise?
TROI: Yes.
PICARD: What happened after the welcoming ceremony?
TROI: There was a reception in Ten Forward. I introduced you to Worf and the other senior officers.
PICARD: Do you have any memory of my calling Red Alert in Spacedock? Do you remember Starfleet diverting us from Farpoint to the Neutral Zone to investigate a spatial anomaly?
TROI: No.
DATA: It would appear there is a discontinuity between the time periods you described. Events in one time period would seem to have no effect on the other two.

Mike drop. Stop acting like you can mess up history, Picard!

CRUSHER: But you've been to the future. You know it's going to happen.
PICARD: I prefer to look on the future as something which is not written in stone. A lot of things can happen in twenty five years.

But you just establised that the past and present timelines aren't the same, can't you also assume that the present and future timelines aren't the same as well? For that matter, now that you know Picard has a brain defect, can't you fix it at this point to stop the Iromodic Syndrome before it even starts?

LAFORGE: Data's arranged for us to run those tests on you in the biometrics lab. We're ready to go if you are.
PICARD: No, no, no. No, we have to get to the Neutral Zone.

We're given the impression that future Picard has problems with deeper thoughts right now because of the Iromodic Syndrome, but you'd think by now he'd learn to keep his trap shut and take notes immediately to sound more coherent.

LAFORGE: All right. Okay. But first, there is no Neutral Zone, remember?
PICARD: Right. Right. Klingons. In this time period, the Klingons have taken over the Romulan Empire.
LAFORGE: Right now relations between us and the Klingons aren't too cosy.

It's an interesting idea: what caused the breakdown of Federation/Klingon relations? Put aside all that Dominion stuff that is still in it's infancy over on DS9 and that the TNG writers probably aren't paying attention to. All I can conclude is that the Duras faction might've succeeded in starting another civil war, winning this time.

LAFORGE: Captain, I'm sorry. I guess all we can do now is wait and see if the Yorktown finds anything.
DATA: There is another option. We could arrange passage aboard a medical ship.

This raises more questions about Data's present state of mind. He has emotions now and feels loyalty to Picard, but he wouldn't volunteer a dangerous idea like this.

PICARD: Is there anything unusual in the vicinity, Mister Data?
DATA: How would you define unusual, sir? Every region of space has its own unique properties that cannot be found anywhere else.

How I don't miss early Data's literalism.

PICARD: Q! We're here! This has gone on long enough! Counsellor, do you sense an alien presence?
TROI: No, sir.

Troi didn't sense Q at first, and with further exposure the farthest she got was that he's a lifeform that's very different from typical humanoids. And even so, I don't think she can read anyone outside the ship unless she can focus on a viewscreen image.

PICARD: Did you create the anomaly?
Q: No, no, no. You're going to be so surprised when you realise where it came from, if you ever figure it out.

Actually, given that Picard was only able to create the anomaly because he was timeshifting due to Q, I would argue that the answer to the question is yes, if it has to be one or the other.

Q: You obtuse piece of flotsam. You are to be denied existence. Humanity's fate has been sealed. You will be destroyed.

A big problem with this whole premise is a simple question: why do the Q care about humanity but not the other spacefaring species? Do they not see the same potential in the Klingons and Romulans that they saw in humanity back in "Hide and Q"?

PICARD: So what am I going to do? Lock myself in a room in all three different time periods?
RIKER: Captain, maybe not acting is what causes the destruction of mankind. What if you were needed on the Bridge at a key moment, and you weren't there?

We already covered this argument back in "Cause and Effect." It's rather tiring to cover it again.

WORF: The Federation Starships Concord and Bozeman are holding position on our side.

Has Bateson and crew really recovered this fast?

PICARD: I know that I'm an old man and I'm out of touch, but the Worf that I remember was more concerned with things like honour and loyalty than rules and regulations. But that was a long time ago. Maybe you're not the Worf once I knew.
WORF [on viewscreen]: Dor sHo GHA! You have always used your knowledge of Klingon honour and tradition to get what you want from me.
PICARD: Because it always works, Worf. Your problem is that you really do have a sense of honour and you really do care about trust and loyalty. Don't blame me for knowing you so well.
WORF [on viewscreen]: Very well. You may cross the border. But only if I come with you. I am familiar with the Neutral Zone.
PICARD: Terms accepted.

At first I liked this scene, but not anymore. Picard is blatantly manipulating Worf and is acting dishonorably.

PICARD: Tea, Earl Grey, hot.
COMPUTER: That beverage has not been programmed into the replication system.

This is complete nonsense. Earl Grey tea is hardly obscure. And even if it isn't part of the standard menu, it would be part of Picard's replicator profile that follows him from ship to ship. Duh.

PICARD: Beverly, I cannot believe that you are not willing to stay here until we
CRUSHER: Don't you ever question my orders on the Bridge of my ship again!
PICARD: Damn it, I was just trying to. Look, there are larger concerns here. What you don't understand is that
CRUSHER: I understand that you would never have tolerated that kind of behaviour back on the Enterprise and I won't here. I don't care if you're my ex-Captain or my ex-husband.
PICARD: You're right. I was out of line. It won't happen again.

A good scene, even if it seems derivative of the Data/Worf scene in "Gambit".

PICARD: My time shifting. The answer does lie there, doesn't it. Now, tell me one thing. This anomaly we're looking for, will that destroy humanity?
Q: You're forgetting, Jean-Luc. You destroy humanity.

Once again Q is being overly literal. Q is causing Picard to cause the anomaly which will destroy humanity.

CRUSHER: This is amazing. The DNA in his optic nerves is regenerating. Geordi, it's as if you're growing new eyes.
PICARD: How is this possible?
CRUSHER: It shouldn't be possible at all. There's no medical explanation for spontaneous regeneration of an organ.
OGAWA: Doctor we've just gotten reports from two crewmembers who say they have old scars which are healing themselves.

This whole thing is just stupid. First, the problem with Geordi's eyes is not his DNA. Second, why are there crewmen on board (besides Worf, I guess) that didn't heal their scars before now?
