There's... something of a discrepancy, Ginko realizes, between incidents he'd known Epsilon had been subjected to here and how many incidents he just indicated happened. One more encounter with fire over instances of being dangerous to others, and then the implication that there's been more than one of the latter means one more of each than Ginko had known about. Which is, to say the least, kind of worrying.

Concern flickers over Ginko's face as he goes over that in his head, and reminds himself not to pry - he's proven enough lately that he can't really be trusted to hold conversations, so if he's going to try... better safe than sorry.

But, in this instance, there isn't really a way to answer without at least skirting around that issue. "...I wouldn't know for sure." He can only assume that, whenever this happened, he wasn't there for it; he's got no idea where it was, and can only guess that none of the many very powerful people on the archipelago were around, given how worried Epsilon sounds about it.
