Editing Tristan (section)

===[[Season 3]]===
In ''[[Bound by One Track]]'', while ''[[Snowpiercer]]'s'' head of departments were in a meeting with [[Asha]]. Tristan whispered to [[Andre Layton|Layton]] that he's needed in the Engine.

In ''[[A New Life]]'', Ruth directs Tristan to make the announcements regarding [[Zarah Ferami]]'s impending delivery, but to not go overboard on the celebrations.

In ''[[A Beacon for Us All]]'', following the successful rescue of [[Melanie Cavill]], Ruth instructs Tristan to prepare a train-wide party to celebrate the last time that they pass by the Pyramids of Giza. Tristan is later amongst the partygoers enjoying himself.

In ''[[The Original Sinners]]'', he stays on ''[[Snowpiercer]]'', which continues to circle the globe. [[Ruth Wardell]], who is intending to go with ''[[Big Alice]]'' to New Eden, hands over responsibility for Hospitality to Tristan as the new Head of Hospitality along with some final words of advice. Tristan takes over making the announcements, telling the passengers that the trains will separate in five minutes.
