While it’s usually other people that spoil things for you, Marvel fans have been spoiled by the YouTube trailer for Agatha All Along, by the subtitles of all things. For Agatha All Along though you’ll want to switch them off though, as the real identity of the twist character “Teen” has already been revealed through them accidentally. If you don’t want to know who this mystery character is I’d advise you to not read any further, unless you don’t care about the spoiler.

Fans have noticed that if you go on the YouTube trailer for Agatha All Along and switch the subtitles to foreign the name “Teen” will be replaced with Billy, confirming this character is indeed Billy Maximoff. Billy is Wanda’s fake son from the WandaVision series, who she lost after lifting her spell in the series finale. He’s all grown up now it seems and slowly becoming the powerful Marvel hero Wiccan, who’s one of the Young Avengers in the comics.
