Warm up

You and Tessa are friends or rather she was your friend (obviously you are both human)...

You fell into Cyn's trap since she took Tessa's body without you realizing it and pretended to be Tessa

And you had been with cyn the whole time and even when they arrived at Copper-09

(in summary in chapter 8 I feel lazy writing) Cyn was standing in the big hole she created and you said through tears while you saw her through your helmet

T-tessa is that you?

And cyn responded

Cyn: "Friend, of course it's me"

Cyn said, pretending to be Tessa's voice

we'll meet again
