I LOVE this question....party because it implies something happening in 25 years.
(spoiler alert)
The original red-room sequence happens 25 years later, meaning that Cooper (older cooper) is there in the lodge and it HAPPENS at that time. The most common perception of this is that the good cooper is going to be trapped in the lodge for that long, while the Doppleganger side of him is out, so Bob can use him.
HOWEVER, since they hadn't planned on anything remotely similar to the Black Lodge when they shot the original red-room sequence, and since the series has never been continued....no one knows for sure if cooper is left there for that long....or if he has to go there at that particular time. If there is ever a continuation, I hope this is something addressed.
There were reports that the next season of TP was going to flash forward 10 years, and continue with Cooper living in TP, and Major Briggs going into the Black lodge to get Cooper out....so, maybe they initially weren't going to make it a 25 year wait for Cooper to get out....BUT you have to take these reports with a grain of salf.
Also coincidence has MOLDED the fabric of Twin Peaks in other situations...and many times, for the better. (take Frank Silva getting in that famous shot by accident)
Now that so much time has passed, if there is a continuation, I believe it WILL be a 25 year later, thingy. THat would be quite interesting, especially since Lynch has said there is more to tell, and Frost has said he is interested.
