["More trouble to walk around."

Bro, you have no idea how.]

Not that I know about - just my brothers, and my sensei.

[But "that I know about" is a qualifier that leaves an awful lot of room for error, and considering the one clue they had to what happened was a truck that drove off and none of them know what happened to it at least until next season...well.]

...I don't know if there were more canisters of the mutagen in that truck, though. Or what they were doing with it in the first place.
