In ONE 17 after teleporting back from Airy's dimension, Liam sees Julien (aka Toothpaste) for the second time. He tells him the radio code for San Francisco, and Julien puts it in and teleports back to earth, or so we thought. What if he put in the code wrong and got teleported somewhere else, and Liam wouldn't know because he was in Airy's dimension. I know it's stupid but its a funny what if.
