In the previous episode, Carrie was interacting with the assistant D.A., and even had a few conversations with him. However, in this episode, they had never met, and she is introduced to him, and he learns of her memory ability. Most likely this is due to them being aired out of order, but it creates a continuity error.
In the previous episode, DA Gilroy worked together with both Carrie and Al to the point of joining them in the van during the sting to take down the head of security for the hotel who murdered the victim. But in this episode, when DA Gilroy showed up at the crime scene, Carrie (who has a eidetic memory doesn't even recognize him).
In this episode Carrie sees ADA Adam Gilroy for the first time and asks Saunders if it's Gilroy. The only thing is that in episode #3 Check Out Time, she interacts with him in connection with charging Maria for murder.
At the beginning, Carrie and Al are on the ground running away from the building when the apartment about 5 flood up explodes. They appear to be blasted over from the explosion. But the explosion way up high wouldn't have affected them. Also they were the only people around the building who appeared to be knocked over by the explosion.
