 When asked in an interview whether she got sick of shooting on the Hydra holding cell set, Elizabeth Mitchell responded I guess so.It was creepy because it was supposed to be underwater, so it was a little bit dingy but kind of great at the same time ... what I will miss is just being one on one with another actor.And then also one on two obviously when it was Michael [Emerson] because the three of us, it was almost like being on stage.
