Lawsuit help

[iron man]

On September 30th of 2010, me and a couple buddies (4 in 2 trucks) finished playing golf and headed to Taco Bell on Lee Dr. We ate, left from Taco Bell, and turned left at a redlight after about 7-8 cars. Well, one car decides at the last minute to make a U-turn where there is no turnaround. Well, this causes everyone to go from 45-50 mph, to break to a dead stop or a slow crawl. We stop behind a crappy little Tacoma that Toyota used to make, still seeing some pavement. I happened to look in the side mirror and see headlights coming full force for the back of my buddy's truck, and I start to say "Oh S..." and boom! We got hit so hard that we got knocked into the Chinaman's Tacoma in front of us, my 7up was all over the dash, my hat and sunglasses flew off my head and into the backseat and our golfclubs were smashed. Well, the cops take about 30 minutes to show up and we all move (under orders from BRPD) from the road into the Winn Dixie/Cane's parking lot. It was Me and Colby, a Chinaman (Tacoma) who barely spoke English, the 22 year (smokin hot LSU student) old (Ford Expedition) who hit us who was texting when she hit us and 2 other people who got in a wreck because of our wreck. The cop takes all our statements and had sorted out who hit who first and what happened next. Well, we were then asked if we were all alright and everyone said yes even though me and Colby caught the full force and was a bit sore and I had to get on a plane in 12 hours and was feeling it when we touched down at SEATAC. Well as it turns out, me and Colby recieved notices today that WE were being sued by the Chinaman because a week later, he went to the hospital with "severe neck pain" and tried to claim that we hit him first and tried to run even though we were wedged in, and that the chick was a bonus accident. We barely touched his truck really and the only damage was his hitch got bent down and Colby's emblem popped off his Tundra on the grille to the front. After reading the report and having insurance companies from all 3 parties involved call me, do you guys think WE have anything to worry about?
