"[3] Alan Sepinwall of HitFix wrote, "Terriers has been on such a roll for the last month-plus that it was inevitable there would be a let-down episode, and 'Agua Caliente' fit the bill.
'Agua Caliente' featured Britt getting snatched up by the Mexican cartel, reuniting briefly with his former partner and then returning to the States in time to help Mark and Hank save Katie's life.
But Terriers has created a world in which everything is connected, as Ray was only south of the border because Britt set him up to get arrested a few episodes ago; while Katie's professor was only involved in her hostage situation because... you know.
