X-Men: Season 3 Episode 19

Weapon X, Lies, and Video Tape

A cryptic postcard unleashes a flood of maddening and painful memories in Wolverine that threaten to drive him insane. To keep his mind from being torn apart, Wolverine and Beast travel to the one location that may hold the answers to his hidden past: the ruins of the top-secret Weapon X lab where Wolverine’s bones were laced with adamantium. There he encounters other former ‘test subjects’—Sabretooth, Maverick and Silver Fox—who are suffering similar mental breakdowns. Later they find out that many of their memories were implanted, and their true memories are destroyed with the lab.
