I mean, seriously. They say Prof. Sycamore is Prof. Oaks grandson, and Blue is too. Also, someone in Lumiose City talked about Prof. Sycamore saying "smell ya later," and who also does that? Blue. Also, you find Sina and Dexio, who are from Kalos, in Alola, but also Blue, whom I think to be Prof. Sycamore in later life is in there, so if you look at it closely, it creates a paradox. If you think I have a fact mixed up with Sycamore being Oak's grandson or something, just answer with the words: Sycamore is not Oak's grandson, and then we can move on.
