The black mask remains fixed on Asriel for a long moment, but if Rinzler did catch that evasion, it doesn't seem like he plans on saying anything. The data he's been provided is useful enough, and gives him an idea what to expect from any future 'monsters'. If the magic accounts for the oddness to his scan, he might even be able to identify what he's looking at.

Assistance: acceptable.
