[As always, Fluttershy has much more trouble talking to actual people than Pokemon, so she seems to shrink down a little, though she doesn't stop the petting.]

Oh, no, not at all... I love meeting Pokemon... She heard me singing and came over to give me company... And I love Mareep, they're so fluffy and cute...

[She could care less about what GLaDOS is wearing, doing, and possibly saying. because cute sheep is cute and hnnnnngh CUTE.]
