"Death Knell" is the 16th episode from the seventh season of military science fiction adventure television show Stargate SG-1 and is the 148th overall.
They soon locate a number of survivors including rebel Jaffa, Tok'ra and Stargate Command personnel, and not long after that they find Jacob who gives O'Neill the prototype weapon.
Daniel and Jacob head back to Stargate Command with the other survivors where Hammond has begun an investigation to find out who leaked the location of their secret offworld base.
Stargate Command launch a unmanned aerial vehicle armed with missiles, however it is soon shot down by the Super Soldier who is hunting Sam through a forest.
Teal'c arrives and draws its attention, whilst Jack is able to retrieve the power source for the weapon from Sam, who uses it to successfully kill the Super Soldier.
One of his main inspirations came from the logging which was taking place around the Mount Seymour Provincial Park, which had previously served as the filming location of the Alpha Site in the season six episode "Allegiance".
[1] For his story, DeLuise continued on from events established in his episode "Allegiance", dealing with the alliance between Earth, the Tok'ra and Rebel Jaffa.
[1] Carmen Argenziano reprises his role as Jacob Carter / Selmak and Dan Payne returns as the Super Soldier.
Vincent-Rudzki felt that whilst it was "probably a credible conclusion" to the Earth, Jaffa & Tok'ra Alliance, he "didn't really care", believing that it was possibly a "money saving" episode.
[16] Paul Spragg for Starburst awarded the episode 2 out 5, believing that writer & director Peter DeLuise "disguises a story that's been done to death as something new and almost gets away with it".
Hoare praised seeing the character in a situation "like nothing we had seen before" going on to write "We’re often shown glimpses of Jack’s special forces training, but this is our first sustained encounter with Sam’s own fieldcraft".
[20] Reviewing for fansite Gateworld, Alli Snow praised the episode, believing it had "terrific balance" between "political intrigue and action".
Snow called Carmen Argenziano "the star of the show" as well as praising the "wonderful" character additions, such as Delek and M'Zel.
[18] Hoare meanwhile wrote "it's tempting to view it through the giddy glee of ‘shipping, but this moment of rare physical affection between the two is deeper and more nuanced than that.
[19] Tapping commented that she originally "balked" at the scene as she felt it made Carter "look weak" and believed that O'Neill would not comfort Teal'c or Daniel in that way.
