Since Jason is Roman and Thalia is Greek, are they Half Siblings atau are they just full siblings?

full
They both have the same mom

Thalia and Jason are full siblings. Zeus and Jupiter are not different people...just two different personalities/forms of the same god.

Not half not full. I'd say 3/4ths.
1/2 for the same mother
1/4 for the father- cause its the same guy, but not.
anda are half siblings if one of your parents are different from your sibling. so if your mom had another daughter, but she had a different dad then you, then you'd only be half siblings

Hmmm...

1. This soalan kinda creeps me out... Cuz... I cant explain it hehe...

2. Weeell, I say... I don't know. If Jupiter/Zeus are two different people, not two personalities in one person... I just confuzzled myself. O.o

Full
Because they have the same mum and dad are the same. Zeus/Jupiter is the same, just different personnalities.

same mom but when Thalia was born zeus was in greak aspect and when jason was born he was roman aspect so they are full sibs

She's the Roman' former Praetor in law

They are full siblings. They have the same mother and the same father. Zues was just in his Greek Form when Thalia was born, and he was in his Roman form when Jason was born. He was the same person, just in a different form.
