I mean it depends on the timeline. Jackson was a host in atleast one other timeline.
Studies have shown that one in four people have been exposed to lethal amounts of radiation and therefore glow green in this meme.
How do we know that’s radiation and not the glow of ascension?
Studies show that 1 in 4 people will ascend, but this condition may not last.
Studies also show that not being a host for a Goa’uld parasite dramatically increases the risk of death.
Death doesnt seem to be an issue for 1 in 4 people, so still pretty good odds overall.
In a clips episode the antagonist, probably Robert Picardo, would use this as evidence to shut down SGC.
Daniel became a host to a Goa’uld in Moebius and was killed by Teal’c
Does getting it on with Hathor and spawning Goa’uld symbiotes also count?
