The building Jason is in during the final Extended Look character switch is the same one seen in this older screenshot from Rockstar's website
Extended look ~19:02 https://www.rockstargames.com/VI/only-in-leonida I just realised that the building shown at the center of the Lucia-Jason switch about 19 minutes into the Extended Look is the same one we can see in corner of this older screenshot from R*'s website. You can see the basketball & tennis courts in the bottom left and also the 7 blue sun shades (?) and the swimming pool at the Hotel Valetta across the street can be used to match the two up. This building is likely important - perhaps a later game apartment etc...? What do you guys think?
