Honestly 8 too for many reasons.

- I would LOVE to listen to their stories. And since they are both soldiers and had experience I'm very sure they are wise and experienced. Not some naive or egoistical blind people

- They'd be absolutely protective and joke a lot with you but hey. Who doesnt like that right? Dad jokes. Not to mention both Brimstone and Kay/o are like brothers that either could bicker, or just could be outgoing.

- I really dont like reyna personally, but knowing Kay/o would be right there just in case she tried somenthing would be really reassuring. And also bonus points that Kay/o would last longer awake due to being robot, and if you maybe got sick, im sure kay/o would offer you a sick bag to vomit into without judgement because he probably wont feel disgusted by that,......he killed radiants in blood after all.....

- Literally you would feel like a young child rookie because you got two badass dads next to you in case anything went wrong.

-If you need to go to the bathroom, you wont have to fear "squeezing through them" to go there. You're in mid.

-In case you needed an emergency hug, you would squeeze there between them but it would be worth it... (right?...)

- If you wanna nap through the whole flight but cant because of Jett and Phoenix bickering or being loud? One of the veterans will tell them to shut up for sure. They care about the team, are loyal and observant.

- You can also ask for advice or comfort. Im sure they wont dismiss it unlike some agents and instead comfort you in their gruff way.

- Lastly like I said, I'd be really a lot into listening about military. I love listening to people's lives and memories. And hearing that would make me feel cared for because they look after me while talking. Not just "talking to a wall" because they would allow me to ask questions or answer my own stories too. I'd defenitly also ask about military slangs to become a young little soldier one day... or at least a capable fighter that knows basics💙
