A rough transcript of the section in question (from around 9min40) is:
Question: Is it possible to do a quad Axel?
Evgeni Pluschenko: Yes, in the future, yes, for sure. I know one guy, uh, who almost made it, the quad axel. So in the future yes.
Q: Have you tried it?
EP: [nods] I tried it.
EP: [shrugs his shoulders, smiles] It's true.
