Mitchell was a member of the DHARMA Initiative, he worked at the Motor Pool.
On the Island
Later, Mitchell was seen carrying tires at the Motor Pool at the background, before Miles and Hurley went to The Orchid, to deliver Alverez's body and lunch. ("Some Like It Hoth") On the next day, he walked in front of Jack, Kate and Faraday when they went to the Motor Pool for guns. ("The Variable")
- Rudy, who portrayed Mitchell, also portrayed another DHARMA member who wore a grey jumpsuit. The member was presented at "the vote" to determine if Sayid should be executed, helped other members to put out the fire caused by young Ben ("He's Our You"), and presented during Horace's speech after the fire had been put out ("Whatever Happened, Happened"). Although the name that labeled on his jumpsuit was hard to determine, it can be assumed that it wasn't Mitchell, and the two were different characters.
Rudy in the Hydra Orientation film
- Beside the above appearances, Rudy also appeared as a new recruit of 1977("Namaste"), and appeared in the Hydra Orientation film("The New Man in Charge"). However, it's unknown who he was portraying in these two appearances.
