I just completed this quest today for the first time, and I was wondering if you can still get her to give you her unique SMG after you complete the quest and she has set up shop in Rivet City? I try not to go to the wiki until after I have done a quest for the first time so I don't ruin it for myself, and I just assumed she would give up her gun when the quest was over. Unfortunately, it didn't work out like that at all. After going to the Vault, I now know I needed a note from her father in order to get her to give me the SMG. Can I go to the Statesman Hotel and get the note, then go back to Rivet City and talk to her again, or have I lost any chance of getting it now?
Thanks in advance for any replies.
edit - sorry for misspelling "Independence" in my topic description.
