They literally focused everything on Will's figure (but honestly no one cared) when we all wanted to know more about Bella's life before coming in S3. She would've brought more secrets, stories, support to the girls and maybe someone trying to out her in the past... we got nothing about it
At least Rikki finally tried, loved this parallel
What some people don't understand is Charlotte's role in her first part of the season and they exchange fake cordiality with real politeness from Charlotte.
It's very obvious how she had to be "good" towards Lewis bc she had a proper goal since her first episode and she saw how much Cleo was vulnerable, working subtly on her weaknesses (trying to get close to Lewis and complimenting him in front of Cleo on purpose in 02x03, forcing Lewis to have a picnic together and challenging Cleo at the end of 02x06, giving Lewis's hoodie to Cleo in order to make her jealous and drive a deeper wedge in 02x08, inviting herself at Lewis's cerimony in 02x09, tutoring Cleo to get her away from Lewis and manipulating him in the whole 02x10, etc.).
She also displayed such entitlement and arrogance towards JuiceNet workers (Emma and Wilfred) in 02x05, wanting that juice at all costs, while interfering between Lewis and Cleo snitching on them.
That is definitely not good person behavior. Cleo, even if she didn't have to read her diary, wasn't so wrong being suspicious about Charlotte.
I loved when the girls were well-coordinated with each other, especially by matching colors and vibes.
