As viewers remember, Mitch first thought Gray was having an affair, but if he is spending more time with the family, will he finally be able to expose Gray for who he really is?
The more Mitch gets involved the more Chantelle will panic her life is about to be turned upside down.
Mitch will find Gray’s therapy card, but how will the couple explain it to the already concerned dad?
If you or anyone you know has been affected by Chantelle’s storyline, please see EastEnders help and advice page here.
EastEnders continues on BBC One tomorrow at 7.30pm.
