I too find it hard to believe that Penny and Oliver seem much more qualified than the F2s, especially in regard to operations - the F2s barely seem able to do an ECG/EEG (or whatever it is). Lenny and Yuki's characters are far to overdeveloped and exaggerated.
I don't mind May, whilst also incompetent, she seems the most normal and natural one out of them! I look forward to the storyline with May and Ruth - I don't think the F2s know about Ruths attempt. Could be an interesting storyline.
Peter: So how many are there? Is it bad? Olivia: Did you eat? Peter: Yeah. Olivia: Well, that's unfortunate.
