Coronation Street spoilers follow.

Next week on Coronation Street, Maria’s world falls apart as Liam suffers an overdose and she discovers that Gary is keeping secrets from her.

Elsewhere, evil Nathan makes his return to Weatherfield, and Alya prepares to say her goodbyes for a while.

Here’s our full guide to 13 big moments coming up.

1. Liam collapses

Liam spends time with Joseph at Paul and Billy’s flat. While searching through the cupboard for sweets, Liam finds Paul’s secret stash of Benzo pills and secretly pockets them.

When Liam returns home later, Gary isn’t in the flat. Gary has got himself caught up with comforting his ex-girlfriend Sarah, who’s still struggling after losing Damon from her life.

Liam is secretly struggling with anxiety and panic attacks. His feelings overwhelm him while alone in the flat, so he takes the pills.

Billy finds Paul’s stash missing from the flat and questions Joseph, who mentions that Liam was looking through the cupboards earlier. Billy panics, but it’s too late as Liam is already unconscious after overdosing.

2. Maria makes a discovery

After Liam’s scare, Maria explains the situation to Billy and Paul by revealing that her vulnerable son has been struggling with his mental health.

Maria heads back home and finds Gary and Sarah together in the flat. Both are looking shifty as they feel guilty over Gary not being there for Liam when he was spending time with Sarah instead.

Maria wants to know what Gary and Sarah are hiding from her, so she secretly places a camera on the side before heading out again.

Once alone, Gary hugs Sarah and they agree that it’s time to start keeping their distance again following their recent near-misses with Maria. They’re unaware that Maria is secretly watching via the spycam.

3. Gary’s marriage lies in tatters

Gary hopes for a reconciliation with Maria after she confronts him for keeping secrets from her. Maria refuses to engage with him, making it very clear that a reunion isn’t on the cards.

Later, Maria confides in Kirk over how much she’s struggling with the Liam situation. She harshly berates herself as the worst mum in the world.
