From Episode 4
I think from this episode, the audience really got to see another part of Robert that was less than desirable. He just comes off as way too self-defensive and it seemed like there was no big deal. When he broke the broom after being berated by Chef Scott I thought Scott would have it in for him along the episode.
I really think Lovely taking 45 minutes to fill in an order was conveiently placed, they just wanted to get rid of her.
After dinner service, Suzanne proved how big of a mouth she really had.
Also, the reason Ramsay gave for eliminating Lovely was harsh, subtle but harsh.
