If you can see them both, it stands to reason that you could help the guy first, and the chick wouldn't be in any immediate danger of imminent death...
I think anything you COULD do that might effect the outcome would make you the target though.
If you had a gun, you could fire it in the air?
Just make a commotion, or like attack with a baseball bat....if you don't mind the danger...they'll stop if they think they could get brained. I wouldn't personally care if someone died. Scum deserves to be taken out. If I were to actually throw myself into attack, I'd expect it would be likely ending for me if I didn't end them. Though with each fuck-someone-up or kill, I think the rest would be less likely to approach you.
It's not like you'd stick around after.
Of course, it would never happen...as much as I'd like to, I'm not usually carrying weapons.
Taking them at distance with arrows would be cool though.
