What Servant Class is Death, Anyway? by Yorae Rasante reviews
Leaving Harry alone is a BAD idea, so Sirius convinces Remus and his cousin Tonks to take him somewhere "safe": no Death Eater would look for him in Vegas. Olga Marie needed some R&R from Chaldea, so was tricked to visit the city. The two wake up married, plus Tonks. Drinks and Elvis may have been involved. ("Fun" fact: not able to set the FGO chars, not available to. Sorry)
