Sergio already knew where Juls lived from the very first time Lucho had him follow Val when he thought she was going to a guys house because he said she never comes to this area, then when Juls walked out to greet her, that’s when Sergio said well at least now I know where Juls lives. This was before they caught them both at the other house. But it is a plothole that Lupe told him where Juls worked but then didn’t know who he was.

Ah, right, that is what we were pointing out, that he knew where Juls lived because of following them but Juls never questioned how he knew. it’s not necessarily a plothole, she had other things on her mind and she could have assumed Val told him or in fact realized that if the boys followed them to Valle, they already knew everything else. But it’s creepy. 

And another anon:

Sergio has been shit this whole time and he lied a lot, now Lucho hacked Lupe’s phone to know where she was who is to say that he didnt do the same to Val during their relationship that’s why he says he always knows where she is in that hospital scene and Sergio knows about this and actually does the same with Juls

Indeed, I saw a bunch of people go ohhh, that’s how he knew she was at the hospital. I don’t think Sergio does it, otherwise he wouldn’t have to ask people so often, lol.

Didn’t Juls keep her phone during the kidnapping? Why didn’t they just track that instead of Lupe’s?
