10/10 blushes this chapter. I was surprised he actually said it straight out, wasn't surprised he fell in, was mildly disappointed at the pun, partially forgave it for her still being flustered afterwards.
Was that helmet on the shelf a Prey reference? This author truly is a man of good taste.
prey or bioshock kinda looks like a big daddy with big arm and slouched.
I'm pretty sure they're referring to the helmet at the top left corner of the second panel (partially out of frame). It is indeed a Morgan Yu figure from Prey.* The Big Daddy is in the panel before that, also in the top-left corner. Below the Big Daddy is a Psycho from Borderlands.
The next shelf down features a Vault Boy, Claptrap, Isaac Clarke, and Tracer. I don't recognize the helmet(?) behind the word bubble.
*The figure doesn't appear to exist in real life, it looks like the artist drew directly from the image I linked.
