The four lions are down. In Castle Doom, King Zarkon and Haggar have a meeting. Haggar predicts that the Voltron Force will be finished off by morning. On Planet Arus, Yurak prepares his forces for a final assault to crush the remaining resistance. Back at the Castle of Lions, Coran managed to send a telegram to Galaxy Garrison. In Galaxy Garrison, Space Marshal Graham is debriefed on the situation. The key is still not there, and they notice a mouse hole, wondering what could chew through solid rock. Pidge leads the team to the mice's nest and sets a trap, successfully trapping them.
