Editing Lothar Frey (section)

===''A Storm of Swords''===
Although House Frey had allied with House Stark at the start of the [[War of the Five Kings]], the Freys angrily return home when [[Robb Stark]], [[King of the Trident]], marries [[Jeyne Westerling]] instead of his [[betrothed]], a daughter of Lord Walder Frey.{{Ref|ASOS|14}}

Lame Lothar is sent by his father to [[Riverrun]] with the response of the [[Twins]] concerning the reconciliation of House Stark with House Frey. He relays the demands that Lord [[Edmure Tully]] is to marry a Frey, and that the choice of the bride will be Lord Walder's. While in Riverrun, Lothar also participates in the funeral of [[Hoster Tully]] as one of the seven nobles sending off his funeral boat, and he tells Robb that [[Sack of Winterfell|Winterfell has been burned]]. Lothar returns to the Twins with Robb's acquiescence to Edmure's marriage.{{Ref|ASOS|35}}

When Robb goes to the Twins to make amends with Lord Walder Frey over breaking his marriage promise, Lothar meets him outside of the gate and behaves in a conciliatory manner. That night, he encounters [[Catelyn Stark]] in the great hall while he is drinking with some of his relatives, behaving politely to her as well.{{Ref|ASOS|49}} However, Lothar is one of the prime engineers of the [[Red Wedding]] massacre that is about to occur, and had planned many of the key details with [[Roose Bolton]]. It is Lothar's idea to use the song "[[The Rains of Castamere]]" as a signal for the slaughter to begin, and he arranges for the crossbowmen to be among the musicians. He also rigs the soldiers' tents to collapse. Lothar assigns various roles for his relatives during the wedding; his half-brother Merrett is to drink with [[Greatjon Umber]] until he cannot stand or fight, a task that Merrett fails at.{{Ref|ASOS|Epilogue}}
