So Frank killed Layla then, all those flash backs with Layla made me want to congratulate whoever actually did it Sam hired him to do it though so technically he's responsible
Spoiler:
Haha yeah, the flashbacks made Lyla less sympathetic as they progressed. Rebecca too!
Speaking of which, who do you think killed her? I like that we've got a new murder mystery (with the victim being an established character) going into the second season.
