Okay, but where is Annabeth's cap?
✨SPOILERS AHEAD✨
Not me, diving into this rabbit hole. Since its disappearance — and lack of reappearance — during s2, this is no longer a minor shift in canon but a full-on plot device with the weight of...well, the sky (potentially).
I'm so curious how they'll treat its reemergence. If Luke will somehow use it to manipulate Annabeth into taking the burden of the Titan's Curse. If Luke will take advantage of it's power in an attempt to fulfill Kronos' demand at the end of s2 ep7, ensuring Thalia's position as the child of the prophecy and as Kronos' champion (hello other brilliant plot deviation). Or perhaps it'll be exactly what it needs to be, a potential anchor keeping Luke tethered to his humanity (you can't tell me this hasn't all been about Annabeth).
Perhaps it'll be all three. With invisibility at hand, Luke can do a lot of damage quickly. Instead of it being a major advantage for Percy throughout The Titan's Curse, I can see it being a significant weakness used against Percy and his friends as they quest to save Annabeth Artemis. Regardless of the timing of its retrieval, I have a feeling we'll see the full consequence of Percy's mistake unfold in s3.
My theory: Either Percy will swipe it at the Smithsonian after a fight with Luke, or we won't see the completion of the cap's "missing arc" until the tail end of s3 after Luke uses Percy's fatal flaw to lure him into a trap (again).
I fully expect it to be a vital detail in some form or another. Possibly bloody, but only time will tell. Can't wait to see what season 3 brings! (Hopefully a verbal confirmation for seasons 4 & 5, if not before.)
What are some of your theories? 👀
