(If you saw a different post earlier, it’s because you’re getting caught in a time vortex and totally not that I got my days mixed up.)
So Young Harry, who was completely baffled by the concept of “comic book store”, can think of nothing more important to ask his future self than “does my mom throw away all my comic books?”. And Old Harry’s response is basically “no, but your wife does, because wives are just like moms, basically, making you get rid of what really brings you joy”.
I could really do without that last panel, honestly. I know they’re technically the same person, but a teenager talking about sex with a strange old man he just met is a bit uncomfortable, and Young Harry’s face really does not help it.
