Charlie was knocked for six last week when his former work colleague and best friend, Megan Roach, was rushed into the emergency department having overdosed on her cancer medication. And it looks like the overdose wasn't accidental... This week, we see Megan sitting by the canal, ignoring Charlie's calls as she writes a letter to her son, Sam. In it, she reveals that the radiotherapy for her cancer isn't working and that she plans to take her life into her own hands. Yet when a passer-by suddenly collapses, Megan's years of nursing kick in and, rushing to help, she ends up back in the ED. There, she runs into Tess, who pleads with her to contact a concerned Charlie - but Megan warns Tess not to tell him she saw her... Distracted Megan mixes up her bags with those of the stranger she helped and Tess later finds Megan's letter to her son. She resists looking at it until the end of her shift when, worried for Megan, she reads it. Saddened and disturbed, Tess pays Megan a visit at home, but Megan threatens to get her struck off! Elsewhere, Adam takes a big step towards recovering from Harry's death after a tense run-in with psychopathic prisoner Jackson. And Kirsty and Tess come to verbal blows over the best way to treat a patient - but soon an injured Kirsty needs Tess's help.
