Byte couldn't scan Loken when Alex was freaking out a little, it would be weird of byte was able to scan it while he was overwhelmed by looking at a Demon. There's no way for Byte to scan it without Alex also looking at it, which he currently cannot do.
Wouldn't scanning it be the best way to understand it and figure out what's it's doing that causes such a reaction so they can better handle it. If Byte couldn't do anything during the panic attack he should have made that more clear, or maybe come up with a plan (dulling all of our senses maybe) or discuss it shortly and say they shouldn't mess with it unless Loken said so than just outright ignore it completely.
Imo, it wouldn't cause any pacing issues, it's just figuring out what the Demons are doing to us, it can still be made ambiguous if it's magic, science or whatever.
