Clean up, aisle four.

After learning more about Jack's plan from King, Tracy suddenly remembers that B.O. had recently gone on a bit of a winning streak at the casino, and was therefore probably in trouble.  (I guess he conveniently forgot that B.O. had already been in trouble and that he had gone to the casino to rescue him.)  Leaving King and the lieutenant behind to clean things up (and here we learn that either Jack has merely been knocked unconscious and is now drooling on the floor, or that being shot in the back creates a blood spot on the floor more commonly associated with someone having their throat slit), Tracy apparently forgets about all of that cartel stuff that King had been talking about before suddenly changing his tune and talking about this "reputable business" that he runs, and leaps into action once more to go save B.O. and Gertie from certain death.
Okay, so maybe not that certain of  a death in that Gertie had already pretty much taken care of things by the time B.O. showed up.  (I'll give the comic this: it was good to see that Tracy didn't know what was going on since he hadn't been there to see it, even if it does mean rehashing whatever happened there over the next week or so.)  With the criminals being carted away to an ambulance (and then to jail, unless it's a prison ambulance.  Then they're both going to the same place.), Tracy begins trying to tell B.O. about Jack's plan and how that system of his wasn't so much a system as a con in which he was but an unwitting pawn.  B.O., of course, will not hear of this, choosing to stick to his system story until the day he dies.  

But wait, there's more!  Look everyone, Ace is back!  And might I say that he's looking quite the dapper fellow in his pinstripe suit (or at least his arm is.  I can't really say anything about the rest of him).  His appearance not only tells me that this story is going to keep going for a little while longer, but that things may not be all peaches and cream in the Playing Card Kingdom.  Not only does he not seem to be aware of King's appearance at the casino, but if you direct your eyes to his cuff, you'll see a small spade cuff link.  This makes me think that each suit (hearts, diamond, spades, clubs, you know, the big four) is its own little gang and that these different gangs have been at war with each other for years and though right now there is peace, there's still a lot of backstabbing and underhanded deals going on and that the King of Clubs isn't as in control of his casinos as he thinks he is.  Watch your back, my liege.  I fear there are evil forces at work.
