First of all, I'm curious to see how this Tony/Nebula in space thing gets fleshed out, just because, they're obviously on the Guardians' ship (what she traveled to Titan in crashed), and while it's not necessarily capable of faster-than-speed-of-light travel, it can still go long distance in comparatively short periods. It's not like if they only had one of our space shuttles to get home. plus I'd have to think there's a decent chance Nebula would be able to chart a course more or less
toward Earth.
the Russos had sporadically all summer been addressing when asked certain characters' Snapture fate that hadn't been explicitly shown on screen, and they'd said that Shuri, BP's girlfriend and mother had all survived. But now we see Shuri's photo included in that array of who's gone. But of course, the characters in that moment also believe Scott Lang is dusted and there he shows up. Also, we now can't deny the possibility that they've been bullshitting whenever they've provided an individual "answer" like that, since they certainly lied about the title
I mean I didn't really have any trouble believing them before on that because the Russos have never really played it like that with the press and the public (as opposed to someone like Steven Moffat). They'll like maybe dodge around answers with a little smirk, they haven't typically flat out lied.
well and as much as "End Game" might be a nice title, I don't see how that would've been spoiler to the degree of being detrimental. Since the start of them making both films Kevin Feige and pretty much everyone there had been very clear on this being a "conclusion" of the first decade. In that regard it seems like a pretty obvious title.
