It would seem that Dr. Slone's paranoia toward Fortnite aliens has paid off in the end. After putting loopers at risk, and getting them to execute a number of tasks, a mole has indeed been found with the IO who has leaked operational information to the alien invaders.Although the identity remains a mystery at the moment, this confirms her greatest fears that the alien invaders are on to the IO's plan and are ahead of them. It would seem that, in addition to a mole within the organization, several NPCs on the island have come to know about the plans as well, and need to be silenced.And if it's war they want, we'll give it to 'em!This season has been a blast so far, had a bit of time so I had to make some art starting with Doctor Slone because she looks amazing!
