Who is Tom? And why was that box under the floorboards?
From the final moment of The Blacklist season premiere, those have been of two of the many mysteries on the show. Even after the box was brought into the open and investigated by the FBI, there aren't clear answers to either of those questions. There's only speculation.
Though, The Blacklist Season 1 Episode 6 did provide insight into both, while causing problems for Red with the FBI and especially with Liz. Will he be able to sweet talk his way out of this one? Probably. He is Raymond "Red" Reddington after all.
