coolartist1110 for Peridot
Peridot used to be extremely self-absorbed, which lead her to underestimate the Crystal Gems continually. Even after defecting to aid the Crystal Gems, she still mainly thought of her needs. Many of her childlike behaviors, particularly her temper and arrogance, stemmed from her over-inflated ego. This is not to say Peridot is incapable of putting others above herself; she is just not used to having others who are willing to do the same for her. The same behavior extends to her admitting something personal. As she spends more time on Earth, Peridot has started developing a more gracious and compassionate attitude. She's definitely one of the more comedically charged gems because of her overconfidence and manner of speaking.

Lapis, allow me to introduce you to my online friend. I met this charming skeleton over here on the Internet with my Earth Tablet device. He invited me to this gathering of anomalies and other oddities to this roleplaying game! You can thank me later for letting you be my plus one!
Hmm, this decision is quite the conundrum indeed. Perhaps we should consult this online forum to see if anyone else procured a solution superior to my own! Oh wow! Would you look at that, not a single reliable source! I guess that means we'll just have to go with my plan!
So you're the inventor Tony Stark, right?! I saw that you were able to create a completely new element on my tablet! It's rather inspiring to see a human go through such lengths just to become a gem like us! And your limb enhancers are genius! Homeworld should have come up with shape-shifting tech like your's long ago! Gems like me are unfortunately unable to alter their physical presence, but you were able to figure out such tech it in a mere 10 years of your first prototype! Ahem...Do you think I could have some? I'm really short so it shouldn't be too hard.
