Gongenzaka looks to be wondering whether or not he should be trying to sense out for the Queen's soul himself at this point- with Zangetsu's exclamation, it's not feeling like a great idea. But it's Papyrus' trailing statement that causes him to blink in abrupt understanding.

Or at least, apparent understanding. All of their thoughts right now, are merely theories for the most part after all. "...That is how the Ringmaster does so," he notes, eyes widening. "But the Winter Maiden was not the Ringmaster- and we have already been told that the move from 'Maiden' to 'Queen' has never taken this path," he adds more firmly.

"So then- who is to say that in defying it, such damage could not happen?"

For all that they are making these theories though, they are still...well. Right in front of the Winter Queen. "...What the question is, is how to reverse such damage, is it not?"

And, he thinks somewhat bitterly as he looks at the Queen, whether or not she'll let them try that.
