His son-in-law faces a Zombie Apocalypse every week on AMC, so it’s no wonder Ian knows guns.
Did not know that he was Anderson’s son in law.. Cool.
ROFL Your right Rick Grimes happens to be his son-in-law. I wish Papa-in-law would tell son-in-law to aim gun straight at zombies down pointing down on the ground as if he is fighting zombie ants. =)
