WARNING: This article may contain some spoilers for The Good Doctor season 4 episode 12. Read at your own risk.

The Good Doctor season 4 episode 13 is set to arrive next week on ABC, with the title "Spilled Milk." Claire Brown's (Antonia Thomas) storyline will be the major focus here. Her personal life will be further fleshed out, especially when it comes to her relationship with her father.

Claire's father hasn't appeared in the medical drama and he'll finally show up in the upcoming The Good Doctor season 4 episode 13. However, this reunion may not be a pleasant one as they could have some discussions on certain matters and there could be a lot of emotional stories coming here.

Based on the synopsis, Claire is blindsided when her father, who hasn't showed up for a long time, appeared at her door. It's interesting to see how they're going to interact with one another since they've been estranged over the past years.

The Good Doctor season 4 episode 13 may bring several changes on Claire, as well as on how she views some things. She likely feels conflicted with her father's presence, but she could have a totally new perspective if ever they talk about their current situations.

Since Claire's mother is already gone, her father is only the parental figure she has. The series is nearing its season finale, which means it is building up more stories ahead -- now with Thomas' character. There could be an unexpected event that may impact how her story moves forward.

But, aside from Claire, Shaun Murphy (Freddie Highmore) and Lea Dilallo's (Paige Spara) are facing more troubles with their relationship in The Good Doctor season 4 episode 13. The former feels disconnected from his girlfriend, which causes tension between them.

Shaun and Lea's lives will change forever after they found out that the latter is pregnant. Shortly after this unexpected big reveal, the previous episode saw the couple contemplating whether they could bring the child into this world. They've been facing a lot of issues and it could affect whatever they have right now.

As seen in the promo of the upcoming episode, Shaun is still unsure when it comes to Lea's pregnancy. He told her that he feels disconnected, leading to a heated discussion. Their relationship has been challenged several times already, but this might be the biggest test for them.

The Good Doctor season 4 episode 13 airs on Monday, March 29, on ABC.
