Work Text:
Chad wakes up the next day, gets ready for the day, looks in the mirror, and screams yeeting himself away in fear; when nothing happens for several seconds, he cautiously returns to the mirror where he finds with horror that he and Alex have switched powers, and while it would be a lot of fun to make all peace happen today, he doesn't want people to know this happened.
But honestly, what Chad does with this ability is up to the author who uses this prompt. And no, I haven't specified how or why Chad has suddenly gained Alex's power or if it's only for the day. That'll be up to you. The reader and possible author.
