Once Kat and Kamiko reaffirmed their convictions to kill it with fire… only if strictly necessary of course. Things moved on somewhat. They still had to wait a while for Sue to recover her energy but nothing else was said. They were all using this chance to also recover mentally from the series of fights they'd been through. It wasn't much but Kat liked to think it helped her at least.
Once they were sufficiently recovered, they set out again, and it wasn't long till they found a new set of patrol rats. Sue dealt with them quickly as usual and they headed on. It was after one more patrol rat massacre afterwards that led them to a new set of Guard Rats. It was still just the four though, and now with more practice, they didn't think it would be a big deal.
