Immediate Out Call, or Wait for Appeal?

What should the PU do at that point? Does he/she rule R2 out immediately for teammate assistance under rule 8-6-5? Or does that rule no longer apply since R2 passed home so she is assumed to have reached it, thereby making her a runner that has already scored? And if that's the case, does that scored runner stay viable for an appeal call even if she touches home because she was assisted by a teammate to do so?

I think the "grabs her, turns her around" part is assistance as opposed to the verbal part; so assisted runner applies.
