(The Proposal)
Malachy reports to Seamus in the confessional that Teresa wants a baby and that they had sex on the fertilizer bag in the shed. Seamus is not interested in the details.
Malachy throws Teresa a surprise proposal party. Teresa is ambushed by a crowd of people at her door including the priest. Malachy lets them in. Jonathan and Mercury tidy up Teresa.
Malachy proposes to Teresa. There is a toast. Teresa finds herself engaged. Fr Seamus can marry them soon.
Seamus secretly sends Malachy to crank up the swamp. Mary's cooking is unpopular. They call for pizza.
The bridge is flooded. The pizza guy can't get through. Mercury wonders if L’il Pete Moss is coming for her. Agnes dares say what they were all keeping to themselves that L'il Pete Moss was never coming.
Mercury fears her career is truly over. Plus she is estranged from her family. Friends. Cat. Who can she turn to? She has nothing.
The swamp enters inside the house. The waters rise quickly. Everyone scrambles for safety, except for Gunter who braves the outdoors to save his beloved stoats from drowning. Mary dashes upstairs to save her draft poems.
Jocelyn comes to the rescue of Wendell, in a boat she crafted from Una's hoarded junk. Wendell won't come without his friends. They climb aboard to safety.
