"If ya do that, then I'll just keep watch, how about that?"

Smell and any magical sensing abilities have problem been enough to pick up Joker's arrival on the scene long before he removes his invisibility so that he can speak up. He's more than a little roughed up, and more than a little ragged... but better than he could be, which is, frankly, dead. Invisibility, running, and lots of work on his healing skills have come in handy for him today. Of course, that means he's utterly exhausted as a result.

It's why he's not volunteering to fling himself right into the fray, but he's here regardless. After all, they're all exhausted. That's no excuse. If Yuya is still alive... That's better than nothing. They'll figure things out, somehow. Hopefully.

He nods to Sans. "I'll stay as backup, just in case yer too occupied." You know, with being their strongest person around, plus Strange, plus, well, everything. He can't fight, but he can watch and, more importantly.. If anything goes too south, then he can keep other people in the loop. It's what the radio in his hands is for. Honestly, it's a good thing he'd found it... although, considering the situation, it might be bad that he found it at all.
