We didn't see Jim get executed in the comic, so it doesn't really contradict in my opinion. Unless we see his corpse or something, lol.Okay, so having seen The Bone Temple earlier...
The film seems to be a short time after 28 Years Later. We get a flashback to "Samson's" past likely at some point early during the outbreak.
Also, the fact that Jim shows up at the end of the movie with a daughter (likely his and Selena's) most definitely decanonizes the IDW 28 Days Later series which implied he was executed for justifiably killing Major West.
Then again, I haven't read the comics yet, so you'll have to gimme some time to check them out.We didn't see Jim get executed in the comic, so it doesn't really contradict in my opinion. Unless we see his corpse or something, lol.
