Addison is far from pleased to be pleased to be paired with oncologist Dr. Rodriguez to save the life of a newborn with a malignant tumour just as she begins to grow paranoid about her 'perfect' relationship with Sam. Violet throws herself into helping a parolee adjust to life after prison, but their interaction has a very unexpected effect on Pete while Cooper proposes that he and Charlotte should start thinking about starting a family. Elsewhere, after a suggestion from Violet and Charlotte, Amelia begins to think that Sheldon could be the solution to her needs.
