In a way, Lionel is about to unknowingly reap the benefits of the fact that as warped as it might be, Adrian Veidt does have a sense of honor. One that despite his immediate personal desire to just walk away and let the situation play out as it will, refuses to let him do so. Whatever bad blood is between the two men, at this moment he is Ozymandias, and a citizen of Baedal needs his help.

The brute needs to be dealt with first, of course, and that cold blade swings suddenly away from its victim's throat as Adrian's foot connects with the back of its knee with a satisfying thunk. Attention now transferred to its own attacker, the being turns and rushes him, only to have Adrian duck away at the last minute, spinning and grabbing at his opponent's weapon arm, using his momentum to twist it until there's an audible snap.
