The older You is still in the Future, but it is no longer bleak and desolate.
Once you have returned the 11 items to their proper time period, the Time Device will be all green and the Lab (12 o'clock) will flash. Use the Lab setting to return to Professor Pendulum's lab on Main Street, and power up the Future Machine again to travel to the restored future. Take the hovertrains (ride their exhausts) to your Sky Home and receive the Island Medallion from your future self.
(Leave the island by using the Lab setting again to get back to Main Street.)
On your first visit using the future machine, you get the time device from your future self, so that you can restore the items that are tangled in time. When you finish and get the Island Medallion, you still have the device. Set it to "Lab" and go back to Professor Pendulum's lab.
you find your self in the future(seconed time)
once you start you just need to keep running and you will find your old self. he or she will be by a sign
As you repair the times on Time Tangled islands, they will show as GREEN on the device. When all 11 times are repaired, they will all be green and the LAB button will flash. Now you select Lab, and you return to the present (outside Professor Pendulum's lab). Use the Future Machine to visit the restored future, and get the island medallion from your future self. (see related question)
When you have returned all the items to their proper times, the dial of the time device should be all green and the "Lab" will flash (12 o'clock). Select that and go back through the Future Machine in Pendulum's lab. After you find your Future Self and get the Island Medallion, repeat the process (return to the Lab) to leave the island.
You have to go back through the Future machine to reach your future self in the repaired timeline. Make your way to "your" sky home in 2059. This is where you get your medallion, from your "future self". (see the related solution question)
To finish Time Tangled island and receive your Island Medallion, you have to return to the repaired future. All of the periods on the time device will be green, and the LAB position (12 o'clock) will flash green. Use the LAB setting to return to Pendulum's Lab in the "present day", then use the Future Machine again. When you arrive in the brighter future, go right and take the lift to the monorail, and get aboard. Use the exhaust from the monorail fan to lift yourself to the next one above, and then to the small round elevator pad. Enter the Sky Home and your older self will give you the Island Medallion. (exit using the LAB setting again to return to Main Street)
nothing you just leave it alone, when you talk to your future self that person should shoo it away
cause you saved the past
