I totally see Kat feeling so bad too because she saw something she wasn't supposed to and made Lia leave. So she will make Lia tea and bring it to her. She'll shake her head when Lia whispers. "I promise, it will just be between us. I didn't even tell Atty what happened" 

I thought it would be. I figure that Kat will be the same way about her past as Lia, the most she would have been, how she found out what she was. 

I just have to figure out what to do the memory on, because most of the really happy ones were in her childhood/pre-teen years.
