Walt: It's Hank. His name is Hank.
Walt is obsessed with names and the power that comes with them, as evidenced by his alias “Heisenberg” and the classic “Say My Name” scene
But Uncle Jack couldn’t care less what Hank’s name is, all that matters to him is that he gets paid and doesn’t end up in jail. So this is a way of pointing out that Walt’s obsession with names is a little misguided; at the end of the day a name doesn’t hold any real power.
