Elidibus casually taking care of Popp when he passes out and doing a really good job of it. He only really gets to let out his nurturing sides with a select few (and even fewer who don't push back on it) so he's going to grow fond of Popp so fast. In return for that trust he'll open up more about himself, his people, his world.

Very soon he's going to just adopt Popp without him knowing.
