He doesn't need to explain. Ankh knew it was something like that, from the bits and pieces he's overheard or that have made it into the things Eiji says in general. And even if they hadn't talked about it, he'd already told him more detail whether he intended to or not. He'd been listening when Eiji talked to Cole.

But this is the first time he's heard the words 'little girl' in it, and suddenly it's too close to home. He finally sits, flopping down not far from where Eiji is but not looking at him. For a moment, all he can do is draw comparisons. How Eiji desperately clings to the memory of this girl where Ankh tried for so long to forget. How both of them yelled at Cole about it regardless. And then about how when he'd lost all his memories from back then, the one thing he'd ended up recalling was someone telling him to protect the weak.

"She'd probably think you were stupid for being like this, too," is what he finally says, before he has a chance to think about how oddly sympathetic that might sound, coming from him.
