EastEnders has shared the first look at Gray Atkins' reaction to Chelsea Fox's pregnancy news.
The serial killer was stunned when his former partner Chelsea revealed she was expecting his child just as he'd begun a proper relationship with long-time flame Whitney Dean.
In several photos from Thursday's (October 21) EastEnders episode, Gray is shown still reeling from Chelsea announcing he's the father of her baby.

Chelsea also twisted the knife by making it crystal clear to a furious Gray that she didn't want him involved in their child's life because of his cruel behaviour.
The two are set for another heated showdown at Ruby's club, where Gray makes a stinging accusation that Chelsea has no idea how difficult motherhood will be.
The pair briefly dated earlier in the year, but Chelsea called things off when she became alarmed over the murderer's aggressive behaviour toward her.
Actress Zaraah Abrahams has already called for Chelsea to be the one to finally catch out Gray for murdering his wife Chantelle Atkins, Tina Carter and Kush Kazemi over the past year.
"I would love that," the star told Inside Soap. "As long as there are no repercussions for her!
"Chelsea is very nosy, she's always going to be investigating because she's quite a selfish person. So I think she will always be up in any of her boyfriends' business. But if she found out about Gray, that would be very explosive!"
With a Christmas wedding on the way for Gray, will someone catch him out before he claims another victim?
New scenes between Gray and Chelsea will air on Thursday (October 21) at 7.35pm on BBC One.
EastEnders airs on Mondays, Tuesdays, Thursdays and Fridays on BBC One.
