3. The cab driver's name is Francisco Fernandez. Now where have you seen that name before?
Try the Breaking Bad credits. Francisco Fernandez was an assistant to the executive producers for 35 episodes. Hat. Tip.
4. Mike's son did a pretty good job hiding his dirty money (OMG, just like Walt!!!)
His daughter-in-law tells us she found a suitcase with money sewn into the lining, which we find out contained the same amount of money Mike convinced Matty to take from Hoffman and Finsky. And while Walt doesn't hide his in any suitcase linings, he does in 1) a heating vent, 2) a vacuum cleaner, 3) a crawl space, 4) a storage unit, and 5) barrels in the middle of the desert.
