What was this scene supposed to convey?

>>280327952 (OP)
She's jealous

>>280328446
She's his blood-related sister.

>>280328456
She doesn't know that yet at this point of the story.

She was blushing in the original SD broadcast

>>280327952 (OP)
Her being best girl. Too bad she was completely forgotten starting from D*stiny, though

>>280328456
Brothers belong to their sister.

>>280328456
Does it even count as incest even when he's literally some genetically re-engineered super human jesus belonging to space living chad race while she's just a normal human? The genetic distance between them might be even greater than a complete stranger from the same region. This was the same logic used in Mahouka.

Cagalli and Lacus are shit

>>280330963
Lacus is shit? She is ZAFT alien so she doesn't shit, while Cagali should poo for being Earthling. Why did Assrun choose Ugly Earthling girl who poops, spite being a son of Zaft and best Zaft warrior?

En arudin Nicol.(Zaft dialect: in memory of Nicol) My life for Plant....

Lacus and Cagalli are the worst Gundam characters. They are both shit. Even Meer the fakr Lacus is a hundred times better than real Lacus. Even Flay is better.

Its been like more than 10 years since I watched it but did she have a crush on him until it was revealed they were siblings?
