I still don't see the way many thing Pterano should be back by now. He was likely meant to be a 1 shot character like Pat, Sue, Elsie, and some others. And if 5 years had passed I still say the kids would be in their younger teens. It's like a lot of other things, time really does not pass in LBT, it looks like it does, but it really does not. Like in Peanuts and many other things. The gang should be much older by now then they are.
