I wasn't going to write here again but I have questions because I think this episode was sloppy, and after all this time Eric deserves much better. So forgive me, but: Why exactly did Ellen try to kill Greg? From the scene in the layout room at the beginning she knew he wasn't the only CSI working the case so the reason can't have been to stop him finding out about her. How did Greg know that she'd switched trucks? He wasn't there when they caught the guy and according to Catherine he was out of contact with the lab. Why did Ellen ring him to say someone was trying to kill her? She had no reason to suspect that she was actually a, er, suspect, making her motivation for trying to kill Greg even more mysterious, unless maybe he was really bad in bed. And who the heck marks on a timetable which bus they want to catch? Picnics in the lab (did she even have a visitors pass? I haven't watched it again), off-screen phone conversations that have to be filled in by the actors, terrible continuity in that bus station scene, cheesy lines, and Eric having to overact to compensate for Dita's flat performance, it left me thinking "WTF?" Sorry but it could have been so much better.
