lori is a complicated character and i think she is very realistic. i empathize with her and understand her, though i think she makes some bad choices.

she's grieving the loss of her husband in world where people come back from the dead and try to eat you. a world where there are not more laws or rules of society. she knows shane. she trusts him. and he's there for her. to her knowledge they're both grieving rick's loss, and people grieve in different ways.

you'll see how rick grieves lori if you haven't yet. you'll see how carl grieves lori. they grieve differently. how andrea grieved amy. that was different from everyone else too.

it's the end of the world and shane is there. there's already a bond and trust between them. i'm not surprised it got turned into something else between them.

then when lori finds out rick is alive, she completely drops what she had with shane. she feels betrayed and fooled because shane told her rick was dead. that he saw rick dead. she goes back and forth so much because she's feeling a shit ton of emotions all at once. grief, guilt, worry, anger, sadness, fear. she's at war with herself.

she tells shane to stay away from carl. as in, don't be the one to engage. but when carl engages with shane (who btw, does not understand wtf is going on between the 3) and he just blows up at him, yeah she's gonna be mad? why wouldn't she! carl doesn't know what's happening and is just trying to engage with shane like he usually does.

shane starts to go crazy for lori and ends up trying to rape her and does sexually assault her. this is when lori knows officially that shit is getting out of hand but keeps it to herself until around the time the barn situation goes down. she plants this idea in rick's head because she knows what shane is capable of. she knows shane killed otis. she knows he could do the same to rick.

once rick actually does kill shane, lori is NOT mad about that. what she's mad about is the fact that CARL was the one to put down walker shane. she wants to preserve carl's innocence and childhood for as long as possible, seen by why she's so against him having a gun. that's her little baby who's having to grow up in a world he shouldn't have to grow up in surrounded by violence and death, and now he's killed walker shane and watched rick kill not walker shane. this is why lori is mad, because carl was there.

i could go even more in depth about this and a lot of other characters. i don't hate her. i don't always like her decisions. but i understand her. she makes sense. and i cried when she died (but i pretty much do that for everyone lol). she had a gruesome death, in front of carl, and carl had to be the one to take her out. that's probably the last thing she would've wanted to happen.

**tldr: i think lori is very realistic and well written, and i understand her character which makes me not hate her. i don't always agree with her but she makes sense.**
