In Avengers: Endgame, to retrieve the aether from the past, Rocket Raccoon uses a device to extract it from Jane Foster. The exact moment wasn't shown in Avengers: Endgame, but it looks like Rocket Raccoon ambushes Jane Foster and extracts the aether.
Question: Did Rocket likely harm 2014's Jane Foster in retrieving the aether?
I recall in Thor: The Dark World that (a) it evoked a kind of self-defence mechanism when she was handled by Asguardian guards (see also How did Jane survive absorbing an infinity stone?), and (b) extracting the aether from Jane Foster wasn't straightforward when she allowed Malekith to take it. I imagine having it extracted unknowingly would be even worse. Perhaps there's more to say about this.
