That's what I'm thinking. It likely would be easy for her to get that from them... but adults have seen far scarier things than monsters.

[Especially when you fight literal monsters daily!!!]

So putting us in a situation like this would certainly generate fear or despair in quite a few of us - she'd likely be able to pick off some she could consume from there...

[Hmm.]

Maybe that's why she presumably hasn't managed to eat any of the others? Because they aren't feeling what she needs them to?
