You hadn't visited Matt since the whole incident, and he always thought you 'lied' about your death even though you were both clearly killed by the same person. Well, that caused you to move to Houston, where you would then work at the meow wolf location, 'Radio Tave' while matt worked at 'Omega Mart'

Just to be a bit teasing with him, and try to Crack something from him, you open a portal into omega mart, and see him unloading boxes, and importing strange items onto the shelves.
