Hmmmm. I wonder if that dubious relationship is related to Wanda shacking it up with Doctor Doom recently (That would make for an awkward "Assist Me" episode, if it's true)
As well. I don't get that Jubilee hint. I think it looks more like Psylocke.
She was a popular character in the 90's, appearing widely in the comics, TV show and most importantly, the Capcom videogames. X-Men: Mutant Apocalypse on the SNES, COTA and MSH in the arcades.
Now, I twigged this when Lupinko said he knew his comics. Psylocke was Betsy Braddock, a British model born with Mutant powers. Like most comic book characters, she was eventually killed, however, when she was resurrected, her soul was put in the body of a Japanese woman. The widely held theory among comic fans for this entirely random change? Her creator, Chris Claremont, had a thing for Asians, hence the Yellow fever
In the tweet about Jubilee's voice actress included Catherine Disher. VA of Jill Valentine, but more related to this, voiced Psylocke in the animated series and Capcom games.
Song lyrics? Misdirection. It's been glaring at us the entire time and it's so obvious when you look at it which is why Lupinko said "No more freebies". Why would Capcom drag in a minor character (And one in a temporary state at that. Vampire Jubilee? Seriously?) over one who has history with the franchise, was one of the characters that was popular as an assist and could also hold their own if needed in MvC2 and is also quite popular in Japan on top of that.
But then theories, speculation, spoon of mortons at the hand, etc.
