She is very similar to her mother.
Sophia use to color her hair and apply minimal makeup which use to disguise her from her original identity.
And this is the reason Jean never recognized any similarities between her aunt and her mother
But now, after Jasper and her grandparents showed the pictures of her mother, it is only when Jean found it.
And it felt something strange…
It is like seeing her mother again. If Jean is not good at controlling her overwhelmed emotions she would have surely hugged Maria and started to cry.
Jasper will surely break down but she felt that he might not act that emotional. Her brother is not all childish and emotional as she thought.
He is already matured enough and can control his emotions. He is not someone she thought..
Moreover, he is already aware that Valdez's are his maternal family since his childhood. And some or other way Jean sensed his reluctance to meet his aunt, Maria.
