Maybe someone can help me out with this, where in MCU canon is it established that Wanda is/was a teenager? I always assumed she was like, early twenties at the start of AOU. I get that she’s had a traumatic childhood but she neither looks nor acts like a teenager, however I’m prepared to be corrected on this?
I do think it’s plausible she was 18 in AoU. I would argue she’s at least coded as being no older than early 20s. However, she can’t be younger than 17, since she was 10 when her parents died and Tony didn’t stop making weapons until 2008. She is likely meant to be a bit older though.
The people who think she’s like still 17 even in IW are either kids themselves who think that that’s older than it is, or people not getting that her being referred to as a kid has more to do with her relative inexperience than actual age.
I figured Wanda was 18ish in CW because Clint made the High School comment to her. And Steve refers to her as “just a kid.” ¯_(ツ)_/¯
It’s a glib line accusing her of being mopey, like a teenager. Clint isn’t literally threatening to force her to go to high school. The CW/IW writers have said she isn’t a teenager in CW.
Steve refers to definitely fully adult men as “son”–it’s just a part of the whole paternal Captain America thing that has been in his character since the very first issue he was created. More than that, IMO the intention behind that line was to show that Steve was also being biased about Wanda, as Tony was when he called Wanda a “weapon of mass destruction”. Tony was dehumanizing her, Steve was infantilizing her. This is confirmed by the writers in the same interview I linked above.
