The warmth in César's voice definitely doesn't go unnoticed. It's like an ice pick in Dabi's chest for a moment. Magne was loved and accepted here, what right did he have coming along and very possibly ruining something that was so good for her? He falters in his steps, mind lost in doubt. He should turn around, tell the guy to forget he had seen him. Threaten him not to tell Magne he'd seen Dabi.

Something.

But he can't. The whole League had missed her. Twice had suffered and blamed himself for so long, Dabi had hated that he hadn't been there to protect her and the others. He needed to see her well and safe. Happy.

"Hm," The grunt was all he could really manage. He had a lot of things he wanted to say but for now it'd just have to wait. He'd be making sure whoever this César guy was that he was good enough for Magne, after he got to see her that is.
