Well, we have lots of guesses on to who it could be. The most common ones being McGucket, Stanley Pines, or Bill Cipher (hopefully NOT the last one)

But considering that Alex respended to "What will happen to Waddles at the end of the summer. Will he stay with Stan, or will he go to live with Mable at their parents." He responded that thinking about that made him cry. So i agree on you hoping Billy Cipher wont die because honestly, He's my favorite character in the show along with Dipper and Stanford. For those who think this is a troll, believe me, its not. Alex Hirash said it himself. Someone may die in the last episode. Im believing its true.
