Months, years? Or maybe just weeks or days. He had to lobby to get Stark's job, which Nathan lost due to "Cutting corners on the Artifact". Then he had to get Walter's tachy-whatzamahoozit-thingy out of deep storage and in working order for his own purposes.

Thanks. So that means that, in the original original timeline, the same people should have gone explode-y as in last night's episode. In which case, shouldn't Henry known what was going on, since he's been through all three timelines?

I wonder if he will somehow keep that savvy, maybe subconsciously, or if he lost it with his memories?

it might make for some fun "how did I know that?" moments.

ah, time paradox

Jon, wasn't that lobbying thing I mentioned from the alternate timeline? Although I suppose it would still hold for this one, except he's not lobbying for Stark's job, but Allison's.

I think you're right, though. Henry would have known about those other deaths (explains his guilty "Oh, I never noticed those guys before"). I think he's still on the same path (time travel hurts brain!). But then again, things still are truly different from how they went down the first time he went back, when Carter wasn't there to stop him, because otherwise Henry would have known that Carter would have tried to stop him and and and *splat*

I think that Henry's position that anything may change next time round may cover things--like a writer-installed handwave. *I* would think only clearly dependent things would change, but Henry seemed to imply more.

Perhaps the combined effect of all the things that happen by random chance perhaps not happening that way again would lead to fairly significant changes in short order?

That was my thinking too. That Henry's comment to Jack was based on his past experiences, his awareness that the differences were fairly unpredictable. And okay, maybe that's a bit handwavy, but it also fits with the fact that apart from Henry and Jack behaving differently, and from the changes wrought by the explosion (or lack thereof), there's a whole bunch of other people making other choices now.

But, hmmm... shouldn't those other guys still have gone explody? And if they had, wouldn't Henry have remembered?

Maybe Henry remembered the scientists dying but chose to act out the mystery of it like it was happening for the first time for him, so as to avoid causing any big ripples?

We don't know how long it took Henry to figure out how to change the past right?

When Jack goes back in time to stop Henry he's not stopping Henry from the 2010 timeline but from a different time line where Kim died.

Correct?

Holy crap, is that right? I think it is!

The Henry that got to live a life with Kim for four years didn't send his mind back, he ceased to exist. The Henry we have now technically only went so many weeks/months into the future sans Kim before he could send himself back to fix things.

Quick, tell the writers!

Sucks for Henry even moreso now.
