Jordan Masterson (regular, seasons 2 -- present) and Nick Jonas (guest star, season 1) as Ryan Vogelson, Boyd 's Canadian father: Though Ryan initially fled when Kristin got pregnant, he returned to be involved in Boyd 's upbringing, and eventually the two reconciled and got engaged (at the end of season 3). Ryan holds liberal views, both politically and philosophically, and he and Mike routinely clash over their fundamentally opposing values, especially when it comes to child - rearing. Ryan wishes to raise his son without religion, hunting culture and nationalism, however, neither Mike nor Kristin agree with this approach. His vegan diet, views on discipline, and what Mike sees as his oversensitivity are an affront to Mike 's beliefs, but Ryan generally enjoys being a thorn in Mike 's side. On rare occasions, Ryan and Mike agree on what is best for Boyd, but this usually puts them at odds with Kristin or Vanessa. Mike comes to reluctantly respect and like his son - in - law for standing up for what he believes and for being a loving husband and father.
