With Wild Wasteland he will get Alien Blaster there (guess from whom), base dmg 100 energy weapon.
Take Veronica as a companion.
Once you get the I could make you care quest from her you will be confronted by some Paladins after she talks to the Elder.
Later on they will confront you again,if you fail to convince the elder,and attack you outside the bunker if you don't have a extremely high speech skill.
The bodies should give up 2-3 Gauss guns and no bad blood with the brotherhood.
I was so mad because i had a 92 speech skill and fell short of resolving the incident without bloodshed.
