"I don’t expect us to drop anything. I just wish there was a little more respect for him. Everyone is acting like nothing happened, and something did. Sebastian is DEAD, Vincent. He died in an illegal battle arena, alone. To a cocky stranger."  (Act like the love of your life was just murdered in front of you and you desire revenge but cannot get the revenge you so badly want)

"Greetings! I'm Primrose. This lump of moody obsidian is my squad leader, Vincent. I want to apologize ahead of time if he gets a little sassy. He hasn't had his nap." (Basically, you're introducing yourself but you also wanna slightly tease your squad leader to get him to lighten up.)

This one isn't really a line, but you need to be able to do this, so bear with me.

Scream. What do I mean? Let me rephrase.
Scream/cry out like you just woke up from a nightmare where you saw your loved one die. Feel free to be creative with this one.
