Lex's nose was bloodied, his cheek red, and his torso most definitely bruised. Robby didn't look a lot better. Neither he nor Robby had been willing to back down from the fight but if they kept going one of them was going to end up in the hospital or worse.
While Lex hated to be a loser, he was going to be the bigger man. He blocked Robby's punch and shoved him away, before holding his hands up placatingly.
