In order of least likely to most likely, here is what might have happened to the missing egg:
- Antalya cooked it, ate it, and cleaned up her mess.
- It got flushed down the toilet.
- It is in the garbage.
- It was hidden in some obscure place without breaking the shell.
- It is smashed in some obscure place only to be found when it begins to stink up the whole house.
Wish us luck :)
