What happens in the Room of Requirement, stays in the Room of Requirement. Until it doesn't, that is.

Another night, another Draco and Harry hang-out at night. You know how sworn enemies are.

Harry, as always, gets up to get some hot chocolate, though his feet take him somewhere completely else.

Once again Harry's going to the astronomy tower in the middle of the night, and coincidentally that's a place Draco Malfoy likes to go as well, so coincidentally they meet.

Nothing could have predicted the monstrosity of a day that was about to come.

Harry is starting to actually get tired at night, but decides one night to still go out, obviously for a random walk that is by no means an attempt to find someone.

Harry is sleepy for once, but goes on his usual trip to the kitchens to get hot chocolate anyway. Hot chocolate is definitely the reason he's out of bed.

Harry doesn't come across Draco on his way down to the kitchens as usual, but he does meet him on his way back.

Harry, once again, stumbles across Draco on his regular trip to the kitchens.

Harry goes out for some hot chocolate in hopes of it making him sleepy and bumps into someone on the way, literally.

Harry can't sleep so he decides to go get some hot chocolate, because why not? He's not the only one out of bed though.
