The part that I thought was strange was the phone call home. She didn’t even know Tony’s phone number. Can keep a sorted tangled web straight in her mind..... but can’t remember her current boyfriend’s phone number. One psycho chick she is.
I don’t think that is so odd - not with programmable phones. You enter the number once then just hit their name to call - don’t forget she had just started dating Tony a few weeks before this - so texting and calls were all done by his name, not number. She didn’t have her phone any longer and was having to dial the number from the jail phone.
I think Tony must have changed his number after she was arrested and he found out about all of her lies.
