Luka's Links
Heard Libra talk about her sometimes but he wasn't to interested. From the two times he's seen Indigo, he can tell she dislikes him but he doesn't care, much preferring to keep his focus on Libra.
She doesn't know much about him, but from what she does know she doesn't like. She's happy that Libra is enjoying going to college but is displeased with the friend she's made in Luke. Even to go so far as to dislike him more then Riot (At least with Riot she knew him a bit more and could trust him enough to do everything in his power to make sure Libra came home happy and in one piece).
