In her current condition she probably can't reason about "feeding tube" but she can feel and emote.
During Wolfson's investigations, Terri didn't get any significant therapy, at hino's wishes. He was stuck with putting her in a basket then concluding she was a vegetable.
There is a thread stating that Terri just today said she wanted to live when she was told her feeding tube was going to be removed.
Did she get some significant therapy since the time Wolfson was her guardian ad litem?
I thought Michael didn't allow her to get any care.
