Your subtitle is WAY better than mine. And thanks for the rec! I clearly have way too many thoughts about said 5 minutes. ;)
Well I think one of the awesome things about this ship (as you intimated) is that even though they're not actually together for most of the movie, you still feel the connection and the history between them, which just makes it so much more subtle and dynamic and interesting than, IMO, Tony/Pepper or Thor/Jane goo-goo eyes.
