Dmitri Johannes Petrov/History

A detailed chronological summary of the life of Dmitri Johannes Petrov.

Backstory
Dmitri became the warden of The Wall over 50 years before the events of the series. No escape incidents took place within that time.

Fleeing the Complex
In the teaser trailer, he talks to his right hand man Grigori Olyat, showing interest in Henry because of Henry's past crimes. Together they decide to capture Henry.

Henry wakes up at the complex, where he finds Dmitri "welcoming" him to his new home. The warden taunts the prisoner by informing him that he would remain at The Wall for a long time, before ordering Grigori to send Henry to a transfer cell.

When Henry attempts to escape, he has a run-in with Dmitri on several occasions.

Presumed Dead
Dmitri hears about Henry’s attempt to escape and raises the alarm. He threatens his men not to force him to take matters into his own hands. When the truck in which Henry tries to escape falls over at the edge of a cliff, Dmitri confronts Henry there. He admits that he’s impressed by Henry’s attempt to escape and orders him to either surrender or get killed. When Henry fails to respond in time, Dmitri moves the truck over the edge of the cliff and leaves Henry, presuming that he was killed.

However, Henry did not actually fall to his death. He survived by clinging and holding on a hole that was in the cliff. Dmitri presumes Henry has died and returns to The Wall while Henry leaves the country (in the original version) or wanders to a bar (in The Henry Stickmin Collection).

Convict Allies
After Henry and Ellie Rose inadvertently prompted a massive prison riot, a fuming Dmitri confronts the two in the yard, just when they are about to flee on a motorcycle. Before he can kill Henry, Ellie knocks him out with a stop sign.

Dmitri manages to survive the hit, but loses a few teeth in the process causing his voice to be quite silent or "buggy" while speaking.

Completing the Mission
Dmitri only appears in the "Pardoned Pals"/"Toppat Recruits" pathways, which both use "Convict Allies" as a starting point. He now speaks in a lisp due to him losing some teeth after Ellie hit and knocked him unconscious with a stop sign.

His army catches up to Henry and Ellie at the Toppat Launch Site, despite there being an ongoing battle between the Toppat Clan and the Government, Dmitri orders his units to ignore the two warring factions and to only focus on capturing the escapees. The Wall military attempt to impede on the duo's progress towards the Toppat rocket, such as blowing out the bridge leading to it.

Eventually, Henry and Ellie board the rocket as it prepares to launch. Dmitri and Grigori board as well, urging the leaders of the Toppat Clan to hand them over to his custody. Charles Calvin, in his military helicopter, arrives to the scene as well, leading to faction friction for the escapee duo.

Henry and Ellie decide to surrender to Dmitri and Grigori, and the former ensures them that they will never see the light of day again. Reginald Copperbottom and the Right Hand Man do not interfere with the two Wall officials, seemingly allowing them to disembark from the rocket. Back at The Wall, Henry and Ellie are shown to have been encased in ice as an extreme measure to prevent any future incidents at The Wall.

Pardoned Pals
Dimitri, along with everyone else in the rocket, were killed by Ellie and Henry when the rocket collapses after its support beams were destroyed, obliterating it and the surrounding area.

Toppat Recruits
Dmitri and Grigori are shot by Henry and Ellie when they decide to proceed with their original mission to join the Toppat Clan. Grigori is killed, but Dmitri was able to survive the gunfire at the cost of his left eye, having Ellie and Henry oblivious about it. When the rocket starts launching, the "Mission Complete" symbol briefly flashes before Dimitri rises and knocks out Ellie.

Furious about his ruined reputation due to Henry's involvement with the riot back at The Wall, Dmitri attempts to kill Henry once and for all. However, he misses a punch and is thrown off the rocket by Henry, leading to his death.
