Tony's not quiet trust does put him at east a bit. There are a million easier ways to kill the human, as Loki is now painfully aware. He can put aside his distrust of the organization for now while still keeping a vigilant eye.

"Me?" Loki almost laughs. "I'm fine, you're the one who fell from the sky and had his heart stop and almost died right here in front of me-" His eyes burn with unshed tears of anxiety and relief. His had goes to Tony's chest to reassure himself he's still there. The new green of the arc reactor shines against his skin.

"I didn't know if it would work, it was all I knew to do. It might not hold forever. Is there a test or a replacement or-" Because what if his magic isn't enough? What if it fails his beloved like it's failed him before?

Beloved?

Shit.
