Physical Appearance

Ruby is 5'1 and is the shortest of all his friends. He is a gentleman. He is of Mexican descent with wavy dark brown hair and brown eyes. He has a chubby face and is mistaken as a child often because of his lacking height. He is averagely built.

Personality

He's a little obsessed with girls and was especially interested in Olivia, who used to live in his house before passing away.

He is what can be described as a "hopeless romantic". This is proven throughout the season by the grandiose gestures he makes for Olivia. Despite being rejected on multiple occasions, he continued to pursue Olivia, in hopes of one day becoming the "love of her life".

He is also a very determined individual. Whenever there is a problem at hand, Ruby is always the one to assess and eliminate it as soon as possible. It is hinted throughout the season that he was somewhat of deep-seated jealousy towards Cesar if the relationship between Cesar and Olivia was anything to go by. He is very insecure and strives to better himself daily, even if at times he is unaware that everyone around him loves him for who he is.

He is described by Jamal as the "wizard of words" because he is a gifted speaker, although his nervous babble when talking to Oscar in Chapter Two lead to Cesar getting "promoted" in the gang and having to take on more responsibilities.

Quotes


  • "I mean, for starters, I’m small. there’s nothing about me that’s even remotely intimidating and, actually, on numerous occasions, I’ve been told that just looking at me makes people laugh. I also don’t do anybody any favors by being the smartest person in the room. And no one wants to feel dumb when they can’t pick up what I’m laying’ down. It’s belittling, you follow? (Jamal & Monse: mm mm) You see? this is what I’m talking about. I transcend the universal plane of thought and linger on the precipice of the celestial realm. I can’t even keep up with myself. But it’s who I am." (Chapter Two)


  • "I'm wearing indigo tonight. [...] I thought we should claim colors to avoid outfit clashes." (Chapter Three)

  • "You got two options.Either come clean to your folks or come clean to your folks. Karma's a bitch, dude." (Chapter Six)
