With Nick seriously injured in hospital, Lisa furiously seeks out Sean, whilst Med feels increasingly side-lined. Sean's revelations lead the team to suspect Nick might have vital information about Holly and Dylan and they desperately wait for him to regain consciousness. Meanwhile, Rob attempts to leave the online forum, but finds it not as easy as he had hoped, and Sam tries to offer Abbie a way out from Vincent. Lisa's focus, though, is entirely on the investigation and she's increasingly convinced by Sean's claims that Nick knows more than he's told her. All Lisa can do is hope that he survives so that she can find out.
