I have a love/cringe feeling during this episode.
One storyline has Frankie and Brick investigating the murder of a woman in 1969 after Frankie finds the deed to their home. She discovers there was a death in the home that she claims they were never advised about but Mike knew. Brick finds the story on his microfiche and though it's a closed case of accidental drowning, he and Frankie think otherwise and on goes their adventure to solve the case. It's comical, especially in the epilogue scene when the Hecks get a more horrifying ending to the case.
Then there is the other storyline with Sue, Axl and Lexie. Sue is the aggravatingly annoying "third wheel" to the couple who can't get a moment to themselves without her tagging along. She then becomes a literal wheel to their Donnie and Marie costumes. The funniest part of the scene is that they assume Donnie and Marie are a real couple, not siblings, but Frankie and Mike's insistence they are finally sinks in. The fallout is great in the end but a little pathetic for Sue.
Always funny!!!
