EastEnders' Nancy Carter struggles to hide what's really troubling her next week, when her behaviour sparks concern.
Two separate incidents alongside the mystery over her return leave her family members confused and suspicious.
Mick Carter no doubt suspects her behaviour could be down to the fact she's only just found out about her secret sister Frankie Lewis, who he only met himself months ago.
He's keen to make Frankie feel like part of the family, and wants the sisters to bond.
Next week, Mick tries getting out some board games in the hope it will allow the siblings to get to know each other after her surprise return this week.
Nancy has been living in New Zealand with husband Tamwar Masood after they left Walford around five years ago.
But what brings her back alone, and Tamwar's whereabouts, all remains to be revealed.
Next week, Nancy is clearly hiding something from her loved ones, and she arouses suspicion with her dad.
Mick is keen to find out what is going on when she fusses over a missing package delivery.
She is determined to track it down, and when it finally arrives she rushes off to get it clearly desperate to retrieve whatever it is.
Worried for her, Mick tries to schedule in some time with his daughter after her return.
Meanwhile, Nancy is clearly on edge when he asks her to look after her little brother Ollie for the day earlier on.
When Ollie suffers a fall in the park, she feels awful having been looking the other way.
But what is troubling her, and what is in the package? Viewers will have to stay tuned to find out.
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
