After going back to their ConjoinVerse house for dinner, Ryan and Bradley discovered that they (their ConjoinVerse counterparts) were going to a costume party that night. Going back upstairs, they found a costume in the closet. Taking it, they went off to the party; it was at the house discussed in the previous chapter (if it is not deleted).
Going inside, the two boys saw plenty of costumes; of course, each had at least two heads. There was a bear with three heads, a snake with two, a knight with three, a vampire with two, and so on. There were a few with four heads, and some had even more. The boys even recognized a few other faces. The nine bros were a hydra--very appropriate. Leo, Donnie, Raph, and Mikey were turtles and seemed to be wearing ninja weapons (no copyright intended). Some people were simply wearing everyday clothes as costumes--clearly they did not plan ahead.
The boys decided to go up to the bathroom to change. Their costume was a ninja with red highlights and scarf. As they were about to put it on, their phones beeped. The message couldn't have been from their own universe--no cell coverage extends that far. Apparently, their phones and those of their counterparts were identical as well, so whoever texted them could have been trying to speak with THAT Ryan and Bradley.
Ryan took his phone out first...
