Well..I actually think it could work. If Tyson shadow traveled with Mrs. O'leary to help them at the Doors of Death, he could sacrafice himself which would not be good for Percy. I could see it happening. And he would reform so it wouldn't be some-what a happy ending, just maybe not at first. Other things I have to say....

1) @Kronos300: I don't think he would be killed since, well he is technically a monster even though he is a sweet innocent cyclops.

2)@ICame2Play: Why would you want to have a long lasting impact? I know I don't want to be sad for awhile after I read the book.

3)@Makurion: I think the fight at Camp Half-Blood won't happen until Gaea is close to waking. In The House of Hades synopsis, it said the Romans will march on CHB in about a month. The book says Gaea will wake in about a month so I think those events might happen around the same time.
