By spending more and more time in the Albufera with Veronica and Sol, Alex delves deeper and deeper into Oscar's former life. Veronica confides to Alex how her pregnancy with Sol took her and Oscar's relationship to a new, almost existential level given how the consequences of having a child together would affect their future lives. At the very least, if the relationship didn't hold, Veronica would be left with the living reminder of it in Sol: a confession that tests Alex to the core, for it is exactly such a reminder of Oscar she has been left without, given their decision to abort 8 years ago due to Alex‘ then skyrocketing career.
