I do think Laurel not telling her father about Sara is very selfish & stupid. I remember MG said that in episode 9 something would happen that requires Laurel to put on the BC suit in episode 10. I'm guessing it was the scene with her mom but I felt NOTHING in that scene & it was so bad! The motivation is not there. I don't buy it. That being said I'm looking forward to her BC arc. Maybe it will make her more interesting & I've been waiting on this for the longest. So far it has been a hot mess but I'm trying to have faith in the writers.
