Future Tense - S2.E13

Oliver is just about to delete Visicron before going to college, but then he is transported into the future by an old man. Oliver gets accused by the old man of being careless with time travel. Oliver and the old man watch clips of past episodes on a screen so that Oliver can defend himself and show the man what good Visicron has done. The old man convinces Oliver he shouldn't delete Visicron and then Oliver gets sent back to the present. We later find out that the old man was really Oliver himself as an old man in the future. In the end right before Oliver leaves to Montreal, Quebec, Canada to go to college he gives Visicron to his 12 year old cousin Simon.
