When interrogating the cheerleader to find out where Madison went, Parker addresses her as Ashley and then a moment later calls her Angela.
The coach shows Nate a photo of the injured cheerleader and says she might be able to breathe on her own one day. The photo shows her with a non-rebreather mask, which only provides supplemental oxygen for someone who is already breathing. If she couldn't breathe on her own, she'd be intubated or have a tracheostomy.
The FBI shows up with a warrant to investigate insurance fraud just minutes after Wendy's assistant withdraws money from their insurance company. That happening so quickly is impossible.
At the start of the episode when the cheerleader falls, Coach Cornell starts compressions when the cheerleader is seen to be able to breathe just fine. Later it is told that she is on a ventilator and cannot breathe by herself.
