In The Big House Pt. 2, Seamus came to Det. Amy Santiago at the public library, offering to give her information on Melanie Hawkins that could exonerate her boyfriend Jake, in exchange for a future favor. In the end, when the Nine-Nine was unable to get anything on Hawkins on their own, Capt. Raymond Holt strikes the deal with Murphy himself to save Jake and Rosa, and stop Amy from taking the deal.
