How can you have a rescue attempt with no heroes in battle? Those two lines seem contradictory on that point.
I know that - I was really asking how it was still a rescue attempt when there was no access in battle. YMT's answer made enough sense, but it raises this question: Is there a current rescuer if the battle goes from RA to BC to no heroes in battle?
