1. Tony is in a relationship with Steve and Bucky. He makes a random comment about his "Uncle Gabe" or "Uncle D," in reference to the Howling Commandos, and Steve and/or Bucky have mental meltdowns because the just realized they would have been Tony's "Uncles" had they "survived." I seem to remember Thor making some comment about gods marrying their siblings, which really doesn't help at all, bless his heart.
2. Clint and Tony are soulmates. Clint helps Tony escape the cave and Tony finds out Clint is the person buying up SI stock (Pepper was worrying about a takeover?).
Thanks very much!
