(CBR) "Lost" and "Deadwood" alum Titus Welliver will reprise his role from the short "Marvel One-Shot: Item 47" in the sixth episode of "Marvel's Agents of S.H.I.E.L.D."
 
Included as a bonus feature on "The Avengers" Blu-ray, "Item 47" introduced Welliver as S.H.I.E.L.D. Agent Blake, who assigns Agent Sitwell (Maximiliano Hernández) to retrieve a Chitauri gun left behind following the Battle of New York and "neutralize" the couple that found it. In the end, Sitwell instead invites the couple to join the agency.
 
Welliver will guest star on the Oct. 29 episode, titled "FZZT," in which floating bodies turn up, leading Agent Coulson and his team to hunt down an elusive killer.
 
News of Welliver's appearance follows Thursday's announcement that ABC has ordered a full season of the series, created by Joss Whedon, Jed Whedon and Maurissa Tancharoen.
