Season 2 question
It’s not really known why she took it, since it’s left vague on purpose. I personally don’t think she’s under the dragon’s corruption, since she’s a firstborn, and they seem to get extra protection. I assume she took the egg to protect it from corruption. She did meet Glint, so maybe she knows more than she lets on.
Nothing indicates that she’s under Mordremoth’s control as she’s been keeping the egg away from mordrem – the moment mordrem arrive in the final episode, Caithe disappears with the egg again fleeing them.
Why she took the egg is still left unclear – keep in mind that Season 2 and HoT are effectively the same storyline, though they’re sold separately. So a lot of mysteries were left unanswered in S2 to be answered in S3.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
It’s all speculation at the moment. I always assumed the dragon could absorb magic like the Elder Dragons and it could be used as such.
That’s the implication – that any dragon can consume and disperse magic like the Elder Dragons, and as such can become Elder Dragons. Glint supposedly could have, but died before she had the chance. Supposedly any of Glint’s hatched eggs could – the egg in S2 is the last egg, the fate of the others unknown (did they hatch or not? dunno; if they hatched did they survive? dunno).
