Dead, worm-ridden mage who flees uphill toward the castle and is run down by Carl.
Lonnie is one of the compromised mages who came through the Doggie Door breach with the Reaver Security Force Cyborg Drop Troopers. After the cyborgs are annihilated, Princess Donut calls out over Warlord Chat to stop him — he's fleeing, and he's the last one.
Carl spots him running supernaturally fast up the hill back toward the castle. He isn't sure Lonnie has any plan at all, but the fact that a dead mage is still moving means there is still a Valtay Worm in his head. Carl activates Daughter's Kiss, leaps off the second story, and lands directly on top of him. Rosetta confirms afterward that Lonnie was the last of them and that the door has disappeared.
