none of them (except Ellen, obvy) knowing that Jo is John’s kid, jo still dying in Abandon All Hope when they go to kill Lucifer... and then being brought back to act as Michael’s vessel.

her agreeing because she’s wanted her whole life to be respected within the hunting world and as a hunter, to be a protector and not the protected. she’s trained for this, for something, and she’s ready. her agreeing because she already died to stop Lucifer once and failed, this is just upping her arsenal, is just committing to that. if she’s willing to give up her life she’s willing to give up her body too.

and she’s really not about to be talked out of it by sam or dean, either. she’s stubborn, she’s made up her own mind, and it turns out she’s their sister anyway (if that’s a recent revelation and didn’t come sooner in the series, in which case layering in the betrayal she’s still working through when it comes to her mother, to that revelation, and the shock of it. and sam and dean’s wide-eyed reactions to it, both of them re-examining their attraction to her and her doing the same, but there’s no time to dwell).
