i think it's unfortunate you cant really discuss the possible connotations of bills abuse of ford in an allegory for sexual abuse because everyone is so quick to defend their triangle when the room for that discussion is very present
i mean even without going into all the metaphorical mess with the possession theres just the straight up nonconsensual public nudity and sexually charged tattoo bill forced ford into getting
would i call the way these are played off in the canon tasteless? yeah. but regardless this did occur
and as for the possession. not only is it literally in this mentality of "you said yes the first time which means you say yes for every single time i do this to you/you cant take back your consent" that is very Indicative of something but this literally is a violation of fords body and control and anything at a fundamental level.
