I actually didn’t realize until posting this that this is the three major versions of Teal’c after joining the Tau’ri. We have bald golden boy Teal’c from the early seasons, hairy Tretonin Teal’c from the late seasons, and then gray streak aged Teal’c from during/after the events in the SG-1 finale.
