Future Ted: [v.o.] That night, Marshall, sat down to write the letter he hoped Lily would never have to read.
Marshall: [v.o.] "My dearest, sweetest, Lilypad. Let this letter be a small beacon, a tiny firefly to help light your way trough the years ahead. My love for you persists, higher than the Himalayas, deeper than a Scottish loch. [sobbing] If I died under suspicious circumstances then beware. Trust no one, not even Ted. Especially not Ted. Know that I'll always be there in your heart, whenever you need me. [sobbing] And my love for you will never die. Love. [sobbing] Your Marshmallow."
