They had been dating for four years after their little speed bump with Frodo and, much to Kili and Fili, the brown velvet box fell to the back of their minds. Frodo became great friends with Fili and Kili who in turn became great friends with Frodo's other friends. They were young and caused chaos and wreaked havoc, leaving Thorin and Bilbo as cleanup crew. Thorin bought a mansion near Bilbo's small house where he stayed with Fili, Kili, Bilbo and Frodo. Bilbo sold his own small house when Thorin bought them a second home close to the mine. Their second home was more of a castle and they spent winters there. Frodo and the brothers had done everything they could think of to get the two engaged but they seemed to be oblivious to their struggles.
