Call The Midwife hinted at the return of popular new character Dr Kevin McNulty at the end of the most recent episode, to the joy of fans.
However, it's not all rosy in Poplar as it seems like there's about to be a bump in the road for the Turner family's adoption plan.
After fostering little May, Dr Turner (Stephen McGann) and Shelagh (Laura Main) decided they couldn't let her go and started the process of officially adopting her.
In preview pictures for the upcoming sixth episode of the series, the Turners are visited by someone from May's past. Is everything about to change?
Elsewhere in the episode, favourite characters join together for a springtime ceremony.
After being estranged due to their busy work lives, Lucille (Leonie Elliott) and Cyril (Zephryn Taitte) are pictured together again. Although, she's still - of course - hard at work delivering babies. Lucille helps Valerie's cousin deliver her little one in the upcoming epsiode.
Call The Midwife airs Sundays at 8pm on BBC One.
