Cyn was once fully possessed by the absolute solver but somehow managed to regain some control, V hated you for some reason, once time you went to find Cyn after she slapped you, wait, more than just slapped you, she damaged the right side of your visor so you couldn't see through that side

Cyn: "Did she hurt you again?...why didn't you tell me?"

you said you always saw her busy

Cyn: "It’s not always that way...let me help you....please!"

then Tessa comes up to Cyn, happy to see her because Cyn is Tessa's favourite drone, you said that it was okay and that she should go with Tessa

Cyn: "I promise to do something!" After a while she came to find you with some news

Cyn: "Where are you?... I have some news...The Eliots are gonna disassemble V..."

you didn't know she was gonna disassemble her

Cyn: "Isn't that good news?..."

you told her it wasn't good news

Cyn: "But she hurt you!"
