Sorry for the delay, it was late, and thanks for hearing me out. Well unfortunately... I lost the first and most important piece somehow, but I still had the other 2 other messages from him which I had the forethought of screenshotting incase I had to prove it.
The first one which I couldn't find on my computer anymore I thought to have said something along the lines of "his tablet having safety features" (I asked him again, turns out I mis-interpreted and he actually just had it taken away for a little bit.)
If this guy is infact a pedo or even an adult, I find it really strange that he's doing chores, going to bed early, and using a tablet which was taken away, by presumably his parents. He has also consistently told me he's 15.
