1st cover up lie - She never arrived.
2nd cover up lie - She died accidently.
Lizzie was only going to stay until 10:00 b/c she had been told a lie by Kat that they had to pick up someone from airport. According to timeline and text she must have arrived 8:55. Lab partner said lab was over @8:15, but Lizzie stayed to go over papers. Plus she had a walk to get to her car.
When AF called and cancelled coming over to apt. with boyfriend and Lizzie agreed to stay longer that's when things changed. I don't think they planned to kill her that night, they thought they only had an hour before their friends were to show up. I think they were scoping her out as a potential sub.or slave to add to their evil little family. Thus if can be believed( the story Kat said) about playing strip poker.
I think Lizzie did say no to kissing Kat and no to watching Kat and Seth having sex. I think he was hoping that she would see them having sex and then want to participate.
I think she was ambushed someway and restrained some way and that is why she was nervous.
I may be way off but when someone is a pathological liar there is always some nugget of truth in what they say. Seth probably did punish het for not finding him a girl while she was in camp and he hounded her to find him a friend as part of her punishment that she could watch him have sex with them ( this is just part of my recollection) not exact quote until they died from orgasims and then he would do whatever he wanted to Kat.
He killed Lizzie to control Kat by following through with the threat and controlling her by fear to never bring anyone over who isn't going to participate.
KAT is just as culpable as Seth. Maybe moreso as she set Lizzie up and we don't know who did what that night b/c she has lied so much.
Still haven't figured out why Roberta was called unless to try to implicate her later if need be.
Just my opinions. Long winded sorry but had to get it off of my chest.
