[The lights are all off when Papyrus gets back to the hotel, which isn't unusual because Sans actually does usually turn off the lights when he's not around. Of course, because it's summer and it gets dark late, it's easy to see the birthday banner stuck up somewhat lopsidedly above Papyrus's bed, the (kind of messily) wrapped present on said bed, and the cake... Attempt... on the nightstand. Also, Sans still glows cyan at all times, and he sits up from his perpetual slouch on his own bed once Papyrus gets in.]
Surprise. [Sans did not even attempt to hide.] Happy birthday, bro.
