That comment about 'Walt's other home'. He's not talking about the laundry. Jesse knows Walt's other criminal associates. Todd, Lydia. Todd'd be a rock in an interrogation, but Lydia? Jesse knows she's a coward and knows how she ships the meth to the Czech Republic.
And Hank? He's sharp enough to figure out the 'Talk or we'll put you in holding and make it look like you talked' play.
This 'other home' business could refer to his home life. As long as Jesse has worked with Walt, the drug making has become their true home, where they both excel at what they do. Perhaps Jesse will be off to tell Junior a few home truths?
I could be a million miles away but either way I'd love to see Junior's reaction to the real truth. He'd be so pissed.
