Desmond's talk with the Oxford workman leads him to the house of a woman named Teresa Spencer. Her sister Abigail has nothing good to say about Daniel when she lets Des in, and we soon see Teresa. She looks like the girl in the photo left behind in Daniel's lab. And sure, to the naked eye she seems to be in a vegetative state, but we know she's simply no longer bound by either time or space. Abigail says that Teresa is "away" right now. Sometimes she wakes up and thinks she's three. Other times she's just talked to their father who has been dead five years. Daniel abandoned her -- ran off to the States, and it's only thanks to a Mr. Charles Widmore than Teresa is getting good care. It seems Widmore was Daniel's benefactor, too; he funded all his research and took responsibility for the disastrous result of it (i.e. Teresa). Nodding toward the personal care attendant and all the medical equipment in the room, Abigail says, "Everything here is due to Mr. Widmore. God bless him."
