[John frowns up at the troll, less in displeasure and more because he doesn't know what to do to fix this. It might not be something that can be fixed, and that's a depressing thought, in and of itself. The world would be a neater place if everything had a ready and prescribed solution.

It would also make life incredibly tedious.]

I'll see what I can do try to mellow him out a bit. He doesn't trust me entirely, either, if it helps. [It hurts to recount this, but he has a point to make.] Bucky doesn't have to trust you unconditionally to be your friend. He just has to trust you enough. The block'll help with that.

[It's helped John's peace of mind.]
