In the end, they may or may not be able to save everyone, and that's just the way of it. In the moment, Horvath is just glad of any help he can get, and watching Hermione and Danny at work is admirable even if the latter seems briefly paralyzed by fear. Maybe especially because Danny seems paralyzed by fear. In light of that, whatever he does manage to do is all the more meaningful.

Now that some of the larger masses of debris have been set aside, Horvath takes a brief break to pick up his cane again and wade closer in. It's too hard to sort through the smaller areas if he can't see what he's doing properly, so this necessitates being closer. If Danny has to go down stairs, that's going to be risky, but there just might be some lower portions of the building that are less collapsed. They can only hope.

He looks for a stairwell and keeps an eye on the rescuers, but then his attention is diverted to carefully shift rubble in the direction of the deep voice that bellowed. Whoever is there sounds like they stand a good chance, if they can be gotten to in time.
