a misfire

The reasoning the characters apply made absolutely no sense to me. If something is bothering you, you talk about it. You don't sweep it under the rug, for years and years. Moreover, just because you had an argument with someone and then they had a fatal accident doesn't mean in any way that it's your fault and that you should blame yourself for that.

Beyond that, when Antia ran away, why didn't Julieta phone the police? Such an easy solution. Or phone the mother of Beatriz? Major loophole there.
