We head back to check in on Jack and Sloane. Jack's leaning against a column, smiling quietly at his old nemesis/best buddy. Jack apologizes to Sloane for never giving his faith in Rambaldi the credit it deserved. Sloane says that he didn't want to shoot Jack, but Sydney forced his hand. "Yes," says Jack. "She can be very stubborn at times." "You're dying," says Sloane. "I can help you." Ah-ha. So here's the part where he wants him to drink from the Holy Grail of Rambaldi Juice. But Jack's not having any of it. "I don't want you help, Arvin," he snots. "You've caused my daughter...so much pain. I could have prevented it. I won't continue to make that mistake." "I think you've overestimated your position, Jack," says Sloane. "You can't hurt me anymore." "True," says Jack, with a smile. "But I can keep you down here with me." Oh, no. Jack reveals that he has a string of plastic explosives in one hand and a detonator in the other. "What are you doing?" asks Sloane with panic in his voice. "You beat death, Arvin," smiles Jack. "But you couldn't beat me." BOOM! Oh holy god. They killed Spy Daddy!
Back with Sydney and Irina "Skating on Thin Ice" Derevko, the glass is still creaking and splitting and Syd is telling her mother that she needs to come back because the glass won't hold her. Oh, let her die, Sydney! She just tried to kill you! In fact, she's tried to kill you PLENTY of times! Including right after you were BORN. Let the bitch die. I mean, I love her and everything, but can you honestly say that Sydney shouldn't just kill the woman and get it over with? Or is this one of those occasions where someone falls on a knife so that Syd doesn't actually have to be responsible for their death? I hate those occasions.
Anyway, Irina tries to move, but the glass starts splitting again, some more, and Syd begs her mother to give her her hand so she can save her, although why she wants to do THAT I can't fucking imagine, and Irina totally ignores her because she sees The Horizon almost within reach and this entire closing moment is RIGHT out of Last Crusade, only it's the child who's pleading with the parent to let it go. Irina can't let it go, however, and she gets her hand on The Horizon, only to have the glass crack beneath her. She falls to her death. Sydney is now an orphan. Vaughn comes out onto the roof and takes Sydney in his arms. They hug as the Vaughn and Sydney Forever love theme plays over the soundtrack.
