@ Sumvates. I'm the same as you. The way Nico describes Tartarus, you'd think no one could survive there. Then all of a sudden Percy and Annabeth fall right down into the chasms.

They are definitely gonna get some help down there, unless their MC plot armor makes them survive on their own somehow. But RR probably knows what his doing, hopefully he comes up with some logical way for them to survive. In the end of the day, I just know that them two are gonna be alive by the end.
