Ain't it made of plush stuffing? I would think he's immune to such things.

Anon the easy copout here is any given immortal can live long enough to change over time. Any observant immortal can adjust behavior, intentionally or unawares, because their intake is all of society, which itself shifts and changes. A mortal human girl, in the dark past, plagued by endless perfect vision and a failing body isn't going to act 1:1 to a modern robot girl freed of her tomb and her wavering omniscience. You're not some sort of detective for noticing she's different and you look stupid grounded so hard in "these can't be the same because she's changed", it's like emotional object permanence.
