'Big Little Lies' news, episode 4 spoilers: Jane's son becomes more aggressive; Abigail moving in with her father causes more conflict for Madeline

Jane (Shailene Woodley) faces more issues in school regarding her troubled son. Meanwhile, Abigail (Kathryn Newton) has decided to move in with her father, which can only cause more problems for Madeline (Reese Witherspoon).

On the next episode of "Big Little Lies," titled "Push Comes to Shove," Jane will be called to school because of her little boy's worsening aggressive behavior.

"Jane meets with Ziggy's (Iain Armitage) teacher, Ms. Barnes (Virginia Kull), who suggests Ziggy be medically evaluated in light of further evidence of classroom bullying. While Madeline is confronted by a skeleton from her past, her internet sleuthing reveals a key player from Jane's past instead," the episode description from HBO reads.

Meanwhile, Madeline will be having problems of her own concerning her daughter's decision to move in with her father.

In episode 7, Nathan (James Tupper) will invite Madeline and Ed (Adam Scott) to dinner to talk about how they can all raise Abigail without causing conflict with each other, but according to Tupper, things might not turn out well.

In an interview with The Hollywood Reporter, Tupper shared how both Madeline and Ed have a hatred for his character for different reasons. Now that Abigail is moving in with Nathan, it only adds to the list why the couple should hate him.

However, Tupper admitted that his character isn't ready yet to parent his teenage daughter under his roof. This could be a good thing for Madeline since it might bring Abigail back with her.

Tupper added that Abigail moving in with Nathan is somehow connected to the murder that happened in town.

"If that didn't happen then the murder wouldn't happen. Everything is all woven together and when you get to the end you'll find out how. ... You realize everything is knit together in this chain of events," Tupper explained.

"Big Little Lies" airs every Sunday at 9 p.m. ET on HBO.
