In Plain Sight Season 2 Episode 4 Quotes

(Closing voice-over) I yearn for blind devotion - unthinking, unwavering - a cause, a thing, a principle worthy of absolute loyalty. A truth self-medicating, a love unabating, something - anything - to which I relinquish all personal responsibility. Semper Fi, 'Til Death Do Us Part', In Nomine Patris, Let's Go Mets. To the true believers, the lucky few, of thee I sing.

Mary Shannon

Oh, and Marshall for the record, I'd sell you out for a twinkie.

Mary
