There were also times when Guille called Val his little sister. Maybe it was just a term of endearment? I think Val is the youngest cause she’s the one who’s still in university.

Yeah, definitely what it seems like to me. 

@fuckyeahpikacha replied to your postwait is guille the youngest? cause i thought Val…

I think when she says hermanito, she means little brother like a pet name rather than meaning younger brother

I guess we are all agreed then!
