Thor realizes, though; can't remember if he found out through simple observation or his Asgardian powers. Thor starts shielding Steve from the most grievous hurts, whenever he can, & Steve's gratitude & thankfulness for Thor's care evolves into romantic feelings. Steve allows himself to feel little & protected & safe in Thor's arms. The fic doesn't have much plot but the idea, & the author's description of Steve's torture, fear, & bitter determination to go on, obviously made an impression on me!
I really hope someone recognizes this fic summary & can give me some info. Help me, Obi-Avengers Fans, you're my only hope! ;-)
