The upcoming episode of "Switched at Birth" season 4 will focus on Lily (Rachel Shenton) and Toby's (Lucas Grabeel) baby shower.
During the second half of season 4, fans learned that Lily and Toby's baby has Down syndrome.
In one of the show's most recent episodes, Lily told Toby and the Kennishes that she wants to go back to London to raise her child with the help of her parents.
Despite their financial problems, the Kennishes offered to support Lily's pregnancy fully if only to make sure that their grandchild will grow up with them.
However, the Kennishes were surprised when Toby and Lily told them that the former will also go to London to be with his family.
Meanwhile, the upcoming episode of "Switched at Birth" will feature Bay (Vanessa Marano) hosting Lily's baby shower, according to Cartermatt.
Unfortunately, not everything will go on smoothly for the family because there will be some issues along the way.
The episode will also focus on Kathryn Kennish (Lea Thompson) and guest star Bess Armstrong's fleeting attraction with one another.
Regina (Constance Marie), meanwhile, will face some problems on her own when she suddenly gets pulled out of Lily's baby shower to attend to an emergency with Will.
Daphne (Katie Leclerc) will be torn between her boyfriend Mingo (Adam Hagenbuch) and the guy who helped him start a deaf school in Mexico.
Additionally, Bay's relationship with a new character (Nyle DiMarco) will also flourish in the upcoming episodes.
"Switched at Birth" season 4 airs Mondays at 8 p.m. ET on ABC Family.
