If 76 registers Sombra's exit from the scene, he doesn't outwardly acknowledge it, overwhelmed by the desire to finish the fight with Reaper while he has the chance. He vaguely understands that trying to exchange blows with someone who isn't fully solid might not be very effective.

But he's not exactly thinking rationally right now. 76 outright tackles Reaper, sending them both toppling to the ground. He wastes no time lashing out again, doing his best to find a place to hold on to, even as Reaper claws at whatever he can reach. The visor helps in that department.

All he can really do is his best to keep Reaper pinned, at least until he has a better opening.
