John and Arthur have had and did have their share of shouting earlier, which is why John is just a wee bit glad that the fire isn't landing on him at the moment. But John is still John, which is why he keeps his eyes on Bucky as he says quietly:

"I'm guessing everything here, all the rules and the dangers... they're new to you. That this place, the things that happen here, even your presence here... it's terrifying.

"But Arthur can't see. He's facing all of this blind. Think of everything you know about this situation. Then cut it down to a third. That's probably twice as much as Arthur can get without help, especially because he usually had me to help him. To tell him everything he should be seeing."

He looks to Bucky.

"And now five months later, he learns something I found out from a glance. Can you imagine all the other doubts and fears and concerns that are rising up right now? All the other things he has to wonder about not knowing?" His lips press flat and shakes his head.

"Describing things isn't just to keep him from falling into holes."
