Yes, great deduction. I'm sure you're right. And note she really doesn't admit to it plainly, you have to put 2 + 2 together to get it and she also throws in the smoke about the extra white Jeeps that could have confused Moul. Angela is a very clever, psycopathic liar and I'm sure she has learned many of her best lies, like throwing in the extra white Jeeps, from her P.R. person Pomeroy who is or was an employee of her attorney Smith who got her the $50,000 lawsuit settlement on her accident that she spent paying off Rick's debts.
Angela said she had her accident a year and a half ago and met Rick a year and a half ago. I'm sure this big lawsuit was a big lure she used to attract Rick. I would assume she settled her lawsuit back around February where Rick knew if he was going to get his bills paid off by Angela he was going to have to marry her. And why not marry a woman that drugs herself out every night after dinner leaving him all alone to go out and do drugs and cat around however he pleases. That's no marriage.
