10 Small Details You Only Notice Rewatching How I Met Your Mother
2. N.Y.C. Lawyer Captures Nessie
Throughout How I Met Your Mother, Marshall has always believed in the supernatural. One mythical creature he particularly loves is the Loch Ness Monster, aka Nessie. He mentions her multiple times throughout the show, and agrees to honeymoon in Scotland just to look for her.
A flash forward scene in Season 3's We're Not From Here teases that Marshall and Nessie may have finally crossed paths after all. We see that Future Marshall proudly displays a newspaper headline, reading "N.Y.C. Lawyer Captures 'Nessie'" in his office. It's not easy to spot, but a closer look at the final moments of the episode should illuminate the article for you. This implies that, after many years of searching, Marshall finally found the mythical Loch Ness monster.
