The Eloise we met as a teenager seems very unlikely to me to ever acquired her advanced scientific and mystical knowledge in other ways. I think she is likely playing a pivotal and probably decisive role in "the war" over the island and the futures of those connected to it.
Interesting take... could be! I definitely think her role is pivotal, as you say.
