This is a question that has been asked many times. One time we lost him for 1/2 hour (!) at the Lights of Christmas deal at warm beach. *shudder*
Shelly, the mother of the birthday boy was doing a quick head count when the question came up: "where's Ethan?" Incidentally, Shelly was with us when we lost him at the Lights of Christmas *shudder*. After searching the facility herself to no avail, she enlisted the aid of some of the older boys at the party to search the facility for Ethan.
Then she started thinking outside the box.
Not too long after that, Ebo was found.
She found him sitting in one of the other private party rooms eating pizza, chips and pop.
There were at least 20 other kids in that room. Ethan didn't know any of them. Didn't matter. Apparently it didn't occur to him that his brothers should be around somewhere. I honestly don't know what is more strange: Ethan following a bunch of kids he doesn't know into a room to eat OR the parents in charge just giving him food. Actually the weirdest thing about it is that it's just not really that surprising at all. If it'd been one of the other boys... unimaginable. Ethan? yeah.... I can see that happening.
The lady in charge of the party Ethan crashed told Shelly that he came in and acted like he was in the right place so she gave him some food. She even let Ethan take his food with him. Of course all the other kids were confused as to why Ethan got to have food and no one else did.
Ethan didn't see anything strange about it all.
I asked him about it in the car on the way home. He started to explain himself, stammered a bit, then just went silent. I didn't press.
Some things have no explanation.
Like this, for instance.
