What would you have done as R2

[REFANDUMP]

Working last night as R2 and have the following play ... bump, bump, set, spike with ball remaining in play (not a legal double first contact, but plays by two different players). Don't know what happened, but an obvious 4 hit play that wasn't called by my R1. I don't know if she froze or what, but everyone in the gymnasium (and obviously the other teams coach) realized that there was an uncalled 4 hits violation. The team that violated won the point, and of course the other teams coach was discussing with me what a fine job my partner was doing at counting to 3 . I decided to discuss the play with my partner and we called a replay. What would you have done as R2 ??
