As the dust settles from events of the last few days, the family find themselves back together at the house for the first time in a while. Deborah and Maurice slip back into their roles as mother and father, for the good of their children, while Donald struggles to come to terms with the fact that his twin sister Amy, like his Dad, might be suffering from a mental illness. Amy is determined to get ready for The Pink Cuttlefish Orchestra's scheduled concert in Omsk, but she crashes down into a depressive state and finds herself exhausted and at a loss. Amy summons the last dregs of her energy to perform, for no one but Hylda, a piece that she has inadvertently written about her own struggle with mental illness. Shun revisits the forest where he once encountered the ghosts of his dead family.

Flowers bows out with a one-off special, stepping away from the present and transporting us instead to a place of peace. Simultaneously haunting and full of hope, this standalone finale breaks with traditional narrative form to give the show's characters the freedom to decide their own fate. Are these images of profound loss, of memories that are now unattainable? Or is it a call to the characters who most need it - that if something was good once, it can be good again.
