Off in the hills, Tommy is, true to Otis's orders, hiking back to TB Village, Charlie once again as his adorable moppet guide. Tommy says that his strategy will be much the same as it was yesterday, only now he's going to "turn on the charm." Charlie wonders what the plan will be tomorrow.

Ed's in surgery, with Ben, Lily, Otis, and Zee all getting a look at the inside of his mangled abdomen. It's definitely more than just the spleen that's been affected. He starts to bleed out, and Otis tells Ben that they don't have more than one packet of AB-negative blood (they're always short on the rare blood types). Ben instructs Otis and Zee to clamp this and work on that, then he grabs Lily and hauls off for the most ridiculous shit I have ever seen. I mean, "an unknown mission."

Mina checks on her charts and sees Old Lady Chest Cold is still sitting on the same bench she was last night. Mina's too busy rolling her eyes at the stupid old lady who won't just go home to notice that she's wheezing and about to keel over. Once she does, the lady is already on the floor. Mina calls for epinephrine and starts doing chest compressions. This is what happens when you scowl at old ladies, people! They die!

So Dr. Ben and Lily are in the jungle, looking for coconuts so they can use the water in them in place of blood for Ed's transfusions. I AM COMPLETELY SERIOUS. To her credit, Lily thinks this is flatly insane. But Dr. Ben drops some knowledge about how coconut water has the same electrolyte balance as blood plasma, and this totally worked in WWII, and besides, he's already done this one whole time before. Um...okay! This is certainly going to make me feel better about myself next time I'm at brunch and I start saying that my blood is 50% piña colada right now. Dr. Ben of course climbs right up the tree (we've already covered motorcycle riding and tree climbing this week -- the show had better pace itself before we get to the vine-swinging and killing boars with his bare hands). He tells Lily she has to catch these -- they're unsterile if they break, and if they hit her on the head, she's probably dead. Because all those Warner Bros. cartoons you watched as a kid were a pack of lies. Lily catches the first, then prepares for number two.
