Plot hole: When Cateleya is in prison she changes into a black cat suit. Where has that come from? Where had she hidden that? She is wearing a very skimpy dress and would not be allowed a handbag or anything.
Plot hole: When Don Luis escapes from his house in the black van he does a high-speed turn out the drive-way and the whole van slides sideways. A few minutes later when he is on the phone he turns to see the 2 dogs sitting behind him. If the dogs were in the van while it was sliding sideways they would have been thrown around the back of the van and would definitely have made some noise, so he would have known they were there.
Answer: Her dress.
