Wait, when did Leon change his mind about val and juls being together? The last thing I remember is him venting to his friend and being pretty upset about it?

I think he was just frustrated about everything changing too fast and him not being able to keep track of what was going on or do anything about it, it was just another thing on a list, and–wait. Do you mean venting in this episode or before, after he first found out? I think at that point he was mostly just shocked and feeling like it was another sign he didn’t know his kid and then there was also the fact that he’s Val’s father in Juls’s father’s body, lol. 

Overall, I think he’s a temperamental dude, his moods seem to influence his thoughts. In last night’s ep, after being in a better place to have a longer chat with his daughter than the last time, he noticed how unhappy she was and well, he’s spied on them enough to know how good Juls is for her. How else should any loving parent advise his daughter? 

Wait I’m so confused help me out. Why was Jacob/Leon tearing up when he was talking to Val about Lucho???

Because he wasn’t actually talking about Lucho, he was talking about himself. He’d just found out that Lucia was in league with Johnny who had him murdered and he was projecting that into both the conversations he had with his younger, easily influenced kids, like the dumbass that he is.

Tbh, that realization made that whole scene far more palatable for me than it’d initially been. I’d only first gotten a summary of it which was of course appalling but there’s a big difference between characters doing bad things and the narrative endorsing them. What he said was terrible, no doubt. But it wasn’t Jacobo saying that as Val’s loving father he thought the best thing in this situation was for Val to consider Lucho’s feelings more, it was a very upset, self-centered Jacobo saying that about himself and Lucia. 

I’m especially glad he had a similar scene with Guille because the audience already knows they should be rooting for Guille/Renata as a cute m/f pair, so their feelings of “wait, Jacobo is clearly projecting and giving bad advice” will more easily be carried into the conversation about Val and, indirectly, Juls.
