Well, after finding Pirate Guy and Skynyrd busy fighting to the deaths with their magic staves, you murder them both by secretly planting an explosive nearby and then detonating it. You then survive all the way till the end but die from the Arena Event.
Well, how did I die? 2 more kills, hoooray!
You went out.... not fighting.... :/ The arena event is a massive storm/haze that blinds the final three people. You accidentally walk off a cliff and plummet to your death, X accidentally activates his "quit the games" watch. Jen wins by doing nothing. This holds true to how the RNG decided stuff. Where you and X walk into "a tracker jacker" nest and die, leaving Jen as a "Luigi wins by doing absolutely nothing" styled winner.
Wow, that is a proud way for Jen to have won. But a win is a win, I guess.
