While hiding behind a marble pillar in the penthouse, void of all light, Xavier was considering all of his options. He had already taken down 2 of the assassins, but he no longer had the element of surprise. He also didn't want things to drag on for too long. The reason for that was, there were too many contingencies that Xavier had to be aware of and attempt to predict. For example, if the electricity came back on, he'd be an open target for any snipers, but that would also mean that backup would arrive. However, if backup did arrive, they may assume he's the enemy and open fire on him. Even he would be helpless against a large group of professionals armed with assault rifles.
So all in all, it seemed as though his best course of action was to act quickly and take down the assassins himself before returning to their boss's side so that she could vouch for him if need be.
But doing so was much easier said than done, which he quickly realised.
