The water was drugged, and Ethan was lying to her to keep the hormonal pregnant woman calm. You saw how she reacted when she was being saved. She was loud and agressive. Why take the chance of her running off. Keep her calm until that night when they take the kid.

Did anyone else notice that in that same sceen, Just like Henry Gale While talking to Sayid, Ethan had to stop himself in mid-sentance and speek again. I got the feeling he was going to say I wish you didn't have to die. Or something very close. As it was, he just changed it to "I wish you didn't have to Go."
