Well if you won one and he won one (assuming the second one didn't count), then you guys should do one more battle?
Especially since you won the initial battle.
The first battle Rock lost.
The second battle Rock lost when he was up 4-2, because of a timeout, and they agreed to redo because the timeout was unfair.
The third battle Rock won.
The fourth battle Rock won.
To me it's fairly clear Rockstar wins that mate, there's no call at all for a fifth battle.
