( Oh— so he does know the name. Peter startles slightly when he hears it; not a jolt of panic or anything so extreme, simply a little surprised motion, one more seen in his face than anything.

But honestly... it seems suiting that Diarmuid would know, that he'd found it out somehow, and it's one less thing Peter has to worry about trying to figure out how to divulge. This whole thing starts to feel less like a confession and more... a conversation. Despite the subject matter being what it is, this is Peter, and his dear friend, sitting and talking together.

He relaxes again, gently, slowly. )

I don't— I don't really understand.... him. Sometimes he's so scary, like this... this thing, but other times...

( Peter's eyes flit to the fireplace again. Through everything he's shared with his dear friend, there are pieces of it he's still kept locked away. )

...I never told you about my little sister, did I? Charlie? ....Has he told you anything about her?

( He doesn't know what all Paimon's gotten up to with Diarmuid, apart from the whole... attempted sacrifice thing )
