Security Chief Paul Hannon Sr. (born in 2231), is extremely aggressive and by-the-book, and he wishes his vault security force was a real military with a war to win. He is not nearly as smart as he thinks he is, and his men are not nearly the crack security force he thinks they are. Spit and polish are everything to him; following orders is his highest calling.
It is likely that Hannon will attack the Lone Wanderer during Escape!, though his attacks are not severely damaging and can be ignored as the quest is progressed through, should one wish to leave him be.
If he lives during Escape!, he will be present during Trouble on the Homefront. He can usually be found patrolling near the Overseer's office. If spoken to, he will blame the Lone Wanderer for the death of his wife and son during the chaos of the breakout incident, but will not attack unless provoked. He dislikes the Wanderer so much he thinks about putting them on a pike - at least he says so.
