Meredith dreams of what her life would have been if her mother had been healthy.

The remains of an escaped convict are found in a residential sewer, but an examination of the sewer pipes indicates that the murder occurred within prison walls. Brennan insists on solving the crime – despite Booth’s pleas for her not to overexert herself – and the expectant couple experiences a very untraditional arrival of their baby daughter.

Frankie and Sue are devastated when Axl informs them that he's not going to church. Mike goes to war with the Glossner kids after they keep defacing his giant inflatable snowman. Brick attempts to wrap his first present.

After doing well in the diaper business, Mike surprises the Heck family with a vacation at Mammoth Cave Kentucky. Frankie suggests the Donahues join them on the trip.

Having decided April isn't good enough for Axl, Frankie works to keep her out of the family Christmas photo, and Sue gets upset when she learns Brick will be working at Spudsy's.

The Hecks find themselves spending New Year's Day attempting to stave off a zombie apocalypse in the Orson Escape Room, while trying to beat the Donohue's record time.
