Peter, of all people, knows that there are times that one simply..... isn't one's self. Trench, like Deerington, clearly has the capacity to cause changes in people. And even if the setting itself can't be blamed in every instance, there are a lot of other reasons a person might suddenly be made very different.

Magical altering items... curses.... some sort of possession. There's a variety pack of options, here, and it's not like Peter knows enough about the man he'd met one single time to be able to properly gauge anything other than the one fact he has to go on. Which is that he was blind then and is able to see again now, something that becomes more evident as the other continues to speak, and gestures downwards.

Peter blinks stupidly again (it's very helpful, really) and with an almost comical obedience, adjusts the bags in his arms and slowly leans forwards to peer down at what the man's referring to. Immediately he gasps, a soft but audible sound, spooked.

"What the— Is that some kind of demon?!"

...Not everything weird is a demon, Peter. He can't help having them almost constantly on the mind, however, and flinches back from the wall. Mouth tipped open, looking both parts confused and hesitant, he asks:

"Wait— so you really can see that thing? I uh... I thought you couldn't... see."

Peter Graham winces, looking pained. In the process of trying not to make it awkward, he's made it extremely awkward.
