The Hughes have said after the fact they were so scared and alarmed the night she eavesdropped that they feared for their children's safety.
I have to think they couldn't have really believed her capable of physical violence , or they would not have joked with Travis many months later about her stalking behavior, which they both did.
If I knew anyone I cared about was involved with the kind of person she revealed herself to be months before she killed him, I would intervene in every way I knew how, no matter the risk to friendship. I can't imagine how any normal person could be expected to sense what she was ultimately capable of, but enough was known about her to be really scary, IMO.
I think Sky warned him at least twice in an interventional way, but he told her she was threatening to kill herself every time he tried to break up with her... this is why we all never know what to make of Travis. I personally keep forgetting she was threatening suicide.
I leaned forward, and firmly said, “She’s not gonna kill herself, Travis, and if she does, so be it! You’d get your life back!” The look on his face broke my heart. It wasn’t one of anger. It was one of pure sadness. He stood there completely defeated. Soberly, he said, “You’re being a b****.”

But you can see, he never listens, JA ruined some trip they all had in 2007, it's kind of strange that Travis thought she'd possibly commit suicide, yet renounced that she slashed the tires or sent that evil letter to Lisa... I think I would have lost it on him a bit.. Sigh, his roommates also tried to warn him, he said he suspected someone was following him... I'm kind of surprised the dog didn't pick up on the break-ins with barking... Naps trusted Jodi? Oy, that poor dog.
