Well we gotta remember, this is the same Terra who confused/weirded out a good chunk of the party asking the question "What is love?"

Celes had a "? The hell kinda question is that?" sort of reaction, other party members weren't sure how to answer—it takes General Leo and SHADOW of all people to get her an answer.

Now, she never quite gets an answer on how to deal with this sort of thing…so she's kinda shooting in the dark.
