Flux Buddies 2.0
In episode 83, on adventure in the Deep Dark, as Kim in in a Flux trance when she found a large area of flux, she got knocked out. She was locked in a tower and Specimen 5 replaced her. Her mission is to extract information from Duncan about the state of their defenses. She also gets a sample of his blood around 17:50 in Ep84. Duncan finds the tower with a sign in it saying 'DUNCAN if you find this I have gone home'. He leaves the tower and finds Bellthorne Bastion in ruins. Duncan leaves Specimen 5 behind, as he is too quick to let her escape. He finds Kim coming over from their base towards the portal. Duncan decided to put the Deep Dark portal somewhere safe - inside another dimension. In Ep97 they find flux oozing out of it. When they enter, there are Taint Swarms and slimes. Duncan places the dimension block inside the meteor in which he was trapped by Lalnable.
