Harm shoots the truck Mac is driving and Mac states he shot the mirror. Later the windshield has no hole in it and the mirror is fine. Later the mirror is changed.
Cmdr Rabb goes into the "torture room" to rescue Mac. He raises his gun and shoots the terrorist in there. The terrorist jerks as if he's been shot and falls to the ground. We see Harm raising the gun and firing and the terrorist jerks and drops dead but the actual gunshot sound is missing.
As Harm and Mac are taking off, Mac reminds Harm how much she hates flying, especially since the last time they went up, they crashed and she was stabbed in the leg ("Full Engagement"). In that episode though, Mac is shot, not stabbed. The comment is also in error as the last time the two went flying was when they flew a MIG-29 and ejected after being fired upon ("To Russia With Love").
