Wait what did allen do? Why is Deculein suspecting him

I forgot too but wasn’t it something with is aura?

When Deculein put Allen to "sleep", he thought that the place he had hit was softer than what was meant to be..

This is just my speculation since there isn't an actual answer yet and even i am confused by it lol.......anyways.....Deculein has the ability of "Iron Man" that activates to make him not only strong/pain resistant to pull through emergency attacks but it could also tell the difference between strong and weak.. so when he knock out Allen the "iron man" ability didn't activate as (weak) but it didn't activate as (strong) either.. he was simply knock out but felt "soft" for someone who works underarm he should have some level of resistance

I didn’t even think about the iron man ability.. makes me wonder what the reason could be but deculein himself doesn’t even know
