Raiden's expression softens into something almost fond at her comments, appreciating Milly's efforts. He's come across the odd person with a prosthetic arm or bionic eye over the years, but nothing remotely as extensive as what he has. As far as he can tell, it's pretty rare, and even if he was the talking type, it's not as though there's anyone around who'd really get it.

Judging by how she reacted to... Well, almost everything, he'd assume the case is similar for Milly too.

"It's the strength," he replies after some hesitation, "that's been the hardest thing to adjust to." He drops his gaze to the ground, not out of embarrassment - not entirely - but rather that it's easier to think about if he's not watching for a reaction, "I've destroyed quite a few doors since I came back."
