Dreadzeddd
Lapis, a gem stucked in a mirror for thousands of years. Feeling stuck and wanting someone else to feel how she felt, so she agreed to Jasper's fusion as Malachite.
Everyone around her thought Lapis was a victim to Jasper, especially Steven. In reality, it really was not like that. Sure she had definitely suffered but Jasper felt those emotions, She made Jasper suffer with her anger and control that it even made Jasper call her a monster than she was but who knows about their relationship in detail but them.
She missed having those habits even when she felt it she didn't want to return but couldn't help this affecting her personality. At first or well second meeting since Peridot's villainous and with her so thats why she was being distant to Peridot then it went to being kind roommates with a tension more than just two people living with each other.. and pumpkin.
However, when she heard about steven's interactions with the diamonds. A panic soar through her, not wanting to be stuck and unable to have control of her own life again like those thousands of years being stuck in that mirror. Being avoidant to Steven and Peridot..
