Spoilers for Agatha All Along, but a question for the Jewish side of Mastodon:

William Kaplan was Jewish. We don't know if Billy Maximoff was Jewish. Is he now Jewish by virtue of inhabiting a Jewish body?

My $0.02: No.

William's soul/spirit was Jewish, not his body.

Clearly, his soul departed when he died and his body was inhabited by another's.
