a result of his living four extra years in Eureka, was how extra smart Carter was this ep

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

In last season's finale, at what point in the future did Henry go back to save whassername the first time?

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", which could take time.

Since Stark losing his job wasn't due to something catastrophic like a death, the DoD might not be in as much of a "rush" to replace him and take their time finding alternate candidates. It took them a month to finally fire him in this timeline, so maybe longer in the alternate one.

Then he had to get Walter's tachy-whatzamahoozit-thingy out of deep storage and in working order for his own purposes.

Well, he seemed to still have an affinity for that book of sonnets, although I prefer him not so savvy. Part of his charm.

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?

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?
