Re: Cass and Bella - she's crazy so expect anything
Susan saw Cass was hurt, and that he was having trouble both dodging and healing. Men were hopeless at multi tasking, and in a situation like this, it was a matter of life and of death.
The reducto at the crazy bitch's feet was a smart move, and Susan chose to back that up with a volley of slashing hexes from her direction. She was still too winded to do too much, but that last Death Eater gave her such a very good idea, when her own breath came back, and she was up for casting it.
She raced to Cass' side. "You look like you could use a hand."
