Then I'll go with you! The sooner she gets it back the better, right?!

[ Usagi said the same thing and he knew then that a quick reaction was needed. ]

I've beat him back once before Sora, I can do it again - if more of you are going, then it won't be a problem!

[ He does care about Naminé. So much. It's just buried right now, angry and guilty that he let this guy go the last time. That he clearly didn't take Arden's meaning to stay away. Arden knew that he'd targeted Naminé and didn't actually do anything that would prevent him from trying again. And so he did try again. Arden feels like he should have known better - him of all people, someone else so tied to the Darkness, so wrapped up in it in the past that he'd done everything possible, destroyed someone to get what he thought he needed. That guilt pours out of him, unguarded from Sora. ]
