Alright, I found the fic. This is way better than some double date with the pet birds.
Explosive Gamble
WWE reporter Charly Caruso just lost over 2 million dollars gambling in various casinos and now she wants revenge...by blowing them up! An enraged Maria Santiago is completely upset after finding out her parents Hector and Rosa were caught in the explosion of one of the casinos that Charly blew up and are now on life support. So Maria calls in Ronnie-Anne to deal with this threat. Also along for the ride are Ronnie's cousin Carlota (mechanical genius) and brother Bobby (disguise specialist). With Ronnie's knowledge and ability to wield many different types of weapons (her personal favorites are the AK-47, grenades and bowie knife), Ronnie and her team are ready for revenge! Unfortunately, in between blowing up casinos and evading the Casagrande/Santiago's, Charly Caruso has secretly managed to befriending (and brainwashing) Lincoln Loud, and now Lincoln will do anything for Charly including killing Ronnie-Anne and her family! Now Ronnie-Anne must find a way to capture Charly Caruso, stop her next bomb (the biggest one yet) from blowing up the biggest casino in the city and knock some sense into Lincoln in that Charly is not the one for him before Lincoln or Ronnie-Anne kill each other!
