"Because, you've not done anything to hurt me. You helped me, in a weird way, get away from SHIELD when they brought me back, you helped get me out of the beast, in a way, I'm indebted to you. So I'll help you get out of this." She said with a gentle sincerity, leaning against Loki's shoulder.
Cap woke, but acted still asleep. He knew what Kara was doing, and how she worked so well. She was gentle with those that needed it, sharp with those that deserved it, and overall a kind and fair person. He knew he loved her for that, and didn't mind how she treated Loki. He probably deserved it after the building and stuff. Whispering very quietly, too much so for either to hear, "You're finally seeing what it's like to speak eye to eye with a woman, Loki. Hope you brighten up a bit."
