2. O'Neill, when the bastard said that not only were there aliens, but the Air Force'd been palling around with them for years.
3. The base doctor when she told him about the aliens that like to crawl up inside peoples' heads--funny how O'Neill left out that part. (Things like that shouldn't exist, but they do, and that's why he wears camo and carries guns and goes to dangerous places--though his siblings have never understood this and likely never will.)
4. His niece Bitsy when she announced that she was going to marry her history professor, despite the man being 23 years older than her. (Turns out the professor's a decent man and a surprisingly good shot and much better company than most of his new in-laws. Still not good enough for Bitsy, but no one would be, really.)
5. Sheppard, when the major sits down in Mack's temporary office and says that he's actually from a year in the future and that Mack had died on the hive ship the first time around. (He's seen madmen and pranksters and idiots, and Sheppard's none of those. There's too much weight to his words, too many things left unspoken.)
