Wiccan, not Wicken. I figure Teen is more likely to be Blackheart if anyone is, with Rio being the deliberate red herring (Green Herring?). What'd be really weird, and frankly WAY too much for the MCU to dare, would be if Rio was Nick Scratch. (Prior to the almost-nookie of ep 4 I'd have been more confident in that possibility, but now it'd be implied incest and I really doubt they'd go there.)
