Breaching protocol [and poaching your partner's call] here would have made you both look better IMHO.

At the least, give him the 'I have a call RTFN' look. After all, he should not call something he did not see. He should have pointed at you here for input before calling anything.

Verbal & non verbal communication should be covered in a meeting between you both before the game.
