The old knight tells Indiana that he's happy to relinquish his post. 700 years is a long time to sit in a cave by yourself. #harrisonford #indianajonesandthelastcrusade
Just then, Donovan and Elsa show up.
Donovan's all, "But which Grail is it, ma-an?"
The old knight tells Donovan he has to choose. Elsa says she'll choose for him, and hands him one of several ornate gold grails. Donovan holds it up and says it's beautiful. Indiana looks like he wants to barf.
Donovan takes the Grail over to a fountain and fills it with water. He's positive he's made the right choice, and he drinks from the Grail. Everyone watches with bated breath.
Donovan starts aging fast—like, turning-into-a-skeleton-in-under-ten-seconds fast. He holds on to Elsa as he wastes away, and she screams in terror.
"He chose…poorly," the old knight deadpans.
Indiana and Elsa go back to the grails. Elsa says the Holy Grail wouldn't be made out of gold—which suggests that she set Donovan up. This girl is cold.
Indiana chooses a plain cup, citing that it looks way more like the cup of a carpenter than anything gold or fancy.
Indiana takes this cup to the fountain, fills it, and drinks. The old knight tells Indiana he chose wisely. Also? He tells him the Holy Grail can't leave the building. More specifically, it can't cross the giant seal in the entryway of the building, back out where Henry, Brody, Sallah, and all of Donovan's goons are.
That's the price of immortality: you never die, but you have to live in a cave that we're pretty sure no pizza places will deliver to for the rest of time.
Indiana fills the Grail with water and runs it out to his dad. He helps him drink from it, and then he pours some of the water on the gunshot wound, which promptly disappears.
Henry takes the cup from Indiana and looks at it. This is what he's spent his whole life looking for. Then he sets it down on the ground as Indiana helps him to his feet, and Elsa picks it up.
Elsa's giddy—kind of unhinged, really—about holding the Holy Grail, and she starts heading for the exit. Indiana tells her to chill out. He reminds her that the Grail can't cross the seal.
