April is unseasonably warm and everyone at Nonnatus bursts outside after the long, enduring winter. Trixie reads magazines in a dusted-off deckchair, Sister Julienne tends her nasturtiums, and Fred helps Sister Winifred set up an easel beside the allotment.
Patsy and Delia lay down a blanket and Patsy attempts to read her novel while Delia makes daisy-chain crowns for them both. Hours pass, the sun peaks in the sky, and Patsy realises too late that Delia has fallen asleep in her lap. She is mortified, but nobody else seems to have noticed, so she continues with Strangers on a Train and hopes nobody thinks anything of it.
Delia is jolted awake not long after by Barbara dropping a deckchair with an almighty clatter. Delia looks apologetic, and Patsy smiles and readjusts her daisy crown.
As the afternoon fades into evening, the Nonnatus collective heads back inside, each more freckled than before. Patsy is folding the blanket back up when Sister Winifred comes over.
"I'd like you to have this," she says, handing Patsy a rolled-up piece of paper.
Unfurling the paper, Patsy reveals a beautiful watercolour of herself and Delia lounged out on the blanket. She can see herself, face caught half in shadow, stroking Delia's hair, shiny in the sun. The gentle curve of Delia's neck as she leans in to the touch. She looks back to Sister Winifred.
"It was a lovely moment." is all she says, pouring away her paint water and bringing the easel indoors.
