The other boy started to come closer to him. But it was no longer in the guise of a boy anymore; all of its features were dissipating into static. When their hands touched, the trees and the ground around them started to fall into the nothingness that surrounded everything.

The river (with no banks to be held back by anymore) started to spill over and touch the boy's feet...

But it wasn't really a boy anymore, either. Its body was splitting apart and it didn't know what parts were its, {NULL}'s, or the other thing's. Time stopped. It felt itself merge with the other thing.
