Dodger takes the kerchief and just holds it while he listens to Beelzemon, watching him with an attentive but unreadable expression. Without breaking eye contact, he idly spits blood into it but not bothering to clean himself up. He is learning quite a bit - every bit of information about 'Digimon' is getting filed away, though he can't say how useful it will be.

"I said people. Not including whatever you are." His tone is dull, although there's a vague note of annoyance in there. "Changes of heart like that will get you killed out in the real world. I hope whatever made you switch sides stays good to you."

By 'the real world', presumably, he means whatever twisted clusterfuck he's involved in back home.
