Though lacking in the force of some of the previous times that Tachibana had shared memories of him, the end result is still a stunned Isaka sitting across from him, hand gripping back very lightly. Though his expression is less of a man that's been thrown down several flights of stairs, and more along the lines of having been told bad news. He frowns. He thinks. He is not overwhelmed by this knowledge, but is engaged with it.

"...so there was one more step above what we thought was involved." He finally pulls his hand away, and picks up his cup of coffee instead, to take another swig of it. "No one knew?"

He can maybe bear having not known something if no one else had known, either.
