When Alfred comes into the ED suffering from pneumonia, Rita tells Charlie to give him antibiotics through a drip, as he is refusing them orally.

When Alfred worsens and becomes critically ill, Rita wants to save him, but Connie won't let her, as Alfred has signed a DNR. Lofty comes in with the DNR as Alfred goes into VF and dies. Connie is straight back to work and it makes Rita suspicious of her behaviour. When Rita does a toxin that reveals a large amount of benzodiazepines in his system, she assumes Connie gave him an overdose when she catches her with the same drugs, and calls the police. Connie is later arrested on suspicion of Alfred's murder.
