YMMV / Ben 10 S2 E4 "Gwen 10"

• Bizarro Episode: We get no explanation whatsoever for whatever the heck's going on, Ben still hasn't returned to the regular timeline by the episode's end, and the rest of the series never mentions this episode ever again.
• Fanon: Some fans believe that in this timeline, since Gwen has the Omnitrix, Ben gets the magical amulet that turns him into "Lucky Boy" and starts developing his own magical powers as Prime!Gwen did. If only to give him something to do.
• Hilarious in Hindsight: Ben 10: Secret of the Omnitrix reveals that Azmuth intended to send the Omnitrix to Max, and Ben got it by accident. This happens in the universe presented in the episode.
