Midway

S4 E17: Mr. Coolidge is the newest member of the IOA and openly distrustful of alien participation in any facet of the Stargate program.  Despite his bias the IOA has entrusted him with interviewing Teyla Emmagan (Rachel Luttrell) and Ronan Dex (Jason Momoa) about their suitability to continue as members of the Atlantis expedition. This does not bode well for Ronan who is next on the list to travel to Earth for questioning. Colonel Carter (Amanda Tapping) concerned that Ronan's temper will explode under intense cross-examination asks an old friend to travel to Atlantis to serve as his mentor - Teal'c of the Jaffa. But Ronan insulted by the implication that he can't handle himself makes no effort to befriend Teal'c and their stay on the Midway station en route to Earth does little to improve the situation. Unbeknownst to anyone a plan by the Wraith to invade the Midway station is about to be initiated and an interview with Mr. Coolidge will be the very least of their problems.
