Todd Grimshaw (Gareth Pierce) is set to make a discovery in upcoming Coronation Street things that could change everything.

Things have been rocky between Todd and boyfriend Theo Silverton (James Cartwright) since his daughter Millie (Kaitlyn Earley) began trying to split them up.

Todd began seeing Theo before learning that he had a wife and children, which left him devastated.

However, Theo insisted that he wanted to be with Todd, and the pair kept their relationship on the down-low for several weeks.

Unfortunately, their love was exposed when Theo’s wife Danielle (Natalie Anderson) caught them kissing.

The revelation that Theo had cheated on Danielle with a man tore the family apart, and Millie has been trying to repair it ever since, though her efforts haven’t been entirely honest.

Earlier this year, she announced she was pregnant in the hopes that it would force Theo to spend more time with his family.

However, it was later revealed that she had been faking it all along.

In upcoming scenes, oblivious Theo leaves Millie panicked when he reveals that he is going to speak to her teacher about the pregnancy.

Having noticed Millie’s behaviour, Todd realises that she is lying about the baby.

Confronting her, Todd tells her it is obvious that she’s not being honest and advises her to come clean to save any further trouble.

As Millie emotionally agrees, Todd advises her to take another pregnancy test and claim that the first one was a false positive, promising that he won’t expose her lies to her parents.
