when roo and Lilith cross paths they both start to fight over alastors, while roo had been almost as bad as Valentino was with angle to alastor she wanted to mend things with alastor as lilith always would be there for alastor and knew what roo had done to him which made her act like a mother lion protecting her cube and alastor was nervous not knowing what to do while he loved Lilith as a mother figure he was scared of roo doing something and wary to trust her when she tries to mend things with him ( charlie: now you know how I feel alastor -_-)
