The ropes!

Carmella has an idea. She remembers in one of the matches she watched earlier seeing rope under the ring. She lifts the apron and shouts "Hell yea!". The rope is exactly where she remembers and luckily right next to the still down Becky. Camarilla then proceeds to tie Becky hands behind her back as she tries to struggle against it but fails. Mella giving a few extra blows to Becky helps with this. With Becky hands literally tied behind her back the victory and both championships are within Carmella reach.
