S2·E14 And it Comes Out Here

Despite Paul Beckstead's misgivings, Vinnie uses Diana's record to start a bidding war in the hopes of selling Dead Dog to a bigger label. When Vinnie signs elusive James Eliot, Newquay offers to buy Dead Dog without Vinnie, Bobby or Diana. Diana balks at Newquay's offer, revealing they used to be lovers. Contrary to Frank's wishes, Vinnie sells Dead Dog to Isaac. Frank warns Vinnie that Newquay has been digging into Vinnie's past. (source: http://www.plasticcow.com/wiseguy)
