As for the subject title, I suppose Blue is the color of one of Abel's eyes :)
Sorry I'm too scatterbrained tonight just to put this all in one post.
Notice that Kria still considers May a close friend. That's in character with her values shown later. Family above all other concerns, friends obviously are not far behind that.
The fact that she is angry makes me wonder if she's going to be pissed at Abel for not being in contact more with his mom. We'll see tomorrow!
