Splitting Up Together

Lena and Martin announce to the kids that Lisa Apple's baby, Annie, is their half-sister, and Martin is surprised when they aren't interested in meeting her. Lena feels the burden of being stuck in the middle between Martin and Lisa but still offers to help bring both families together. Meanwhile, Mason overhears Lena and Martin's conversation about Lisa's financial difficulties and decides to start a fundraising campaign to help. Elsewhere, Lena feels a bit of empty nest syndrome when she attends Mae's college fair at school.

In an effort to connect with their kids and bring the family closer together, Lena and Martin plan a fun outing, only to be interrupted by a blackout. Elsewhere, Lena urges an overdue Maya to get induced but must succumb and honor her birthing plan. Meanwhile, Martin continues to try and figure out where his relationship with Lisa stands.

Milo complains that Grandparents Day is coming up at school and doesn't feel Henry is interesting enough to participate. Lena and the kids urge Martin to reconnect with his long-estranged father, Brock, to rebuild their relationship. Meanwhile, Lisa continues to struggle financially and considers moving back home with her parents. Elsewhere, after listening to a true crime podcast, Maya worries that Frank has a dark past he has been hiding.
