[Ren hasn't talked to the person who started this whole mission, but he figures someone must have handed out the net, so he taps his chin.] I guess the person who told you to catch them...? Though I think you should be able to catch more than one at a time if you're careful.

[Assuming the creature doesn't fly out at the first chance it gets, which seems like a potential concern.] It'd be nice if they gave you something other than the net to keep them in while you catch more...

[If physical contact with them is such an issue, it seems like a much safer option.]
