Paul Walker is returning to The Fast and the Furious franchise. He's just not entirely sure why.

“I don’t know,” Walker replied to MTV when asked about his reprisal of Brian O'Conner. “I thought it would be fun to go back and do it one more time to close it out.”

The actor continued to think out loud about the upcoming Fast & Furious.

“When I did the second one everyone said ‘What’s up with Vin [Diesel]? Why didn’t he come back for the second one?’ And then I didn’t do the third one everyone was ‘Why didn’t you do the third one?’” Walker said. “But now everyone is going to be ‘Where’s Tyrese [Gibson]?’ I fought for that, to have him on board and it just didn’t work out.”
