Most cross over events I have seen like the tmnt/batman crossover and the green lantern/Star Trek crossover is easily explained with alternate realities....but one I'm puzzled at is the Lumber Janes/Gotham Academy crossover. I have yet to read it but I want to know just sorta one thing. How did they meet? If it wasn't through a dimension portal but just stumbled upon each other does that mean by technicality Lumber Janes belongs in the same universe as Gotham Academy just under a different company?
