It's been so long since talky landed on the island that she barely even remembers being human, and will probably just deny it. As far as she's concerned, she's midget through and through except for the occasional accidental ingestion of bad Deathor cake that makes her hallucinate all sorts of improbable conditions.
She is generally friendly and talkative, but has an appalling memory, so may stare at you blankly when you meet again. Or, more likely, just pretend she remembers and then be all awkward. This is especially true after her recent long absence. Feel free to ask her where she's been, but she'll only make it up.
