Thor and Vision
Happiness was important. And it wasn't wrong to want that for one's self - if it came at the cost of hurting others, that's where the problem lay but this wasn't that. This was a new beginning, a little spark of hope and promise - maybe they were all technically chess board pieces in this universe (and free will - up to a point - seemed like a far-off concept), but they were still unique and deserved to find things which brought them joy in the time they had.
"I am very glad to hear it," Vision smiled warmly. "And I am certain our paths will cross more often, now that you are here and our fates seemed intertwined." There was a lot to look forward to regardless - he chose to see the potentials, the possibilities, the good in this life.
It was better than being a pawn of S.W.O.R.D., at least.
"Though I will not keep you any longer currently. I am sure you have important matters to attend to inside. Thank you, for showing me around."
