This is bad.

Vanya has seen people die before, including friends. It doesn't make it easier to take in the sum of the slashed throat, the lack of a pulse behind it, obvious up close. If the battle were fully over, he might chase Thot away out of respect, but they're not done, and stopping to mourn might mean more corpses. So Vanya does what he does best: he compartmentalizes. Ellis is dead. That is for later.

For now, he snaps back to attention, moving for Abby and her opponent.
