Optimus Prime has it rough. He's the team leader and thus has to make the hard choices, including what is best for his team. If Prowl jeopardizes them, this could sit very ill at ease for them all. Yet Optimus is also a compassionate guy who cares deeply for his friends. Granted, Sari had to yell at him, but is why he's taking votes.
Sari is the most vocal at the moment (with Bee a close second because he is an impulsive idiot who is very emotionally hurt for what Prowl did) because this takes place during Season 2. Her father is missing, she's kicked out of home, and Optimus' crew was at a risk of leaving Earth at one point. She clearly does not want her family to split up. It frightens her.
Yes, and you know what frightens me? Butterflies. I am NOT JOKING, those things just creep me the heck out.
But I can understand why Sari's like this. She doesn't want her family to get any more separated than it already is.
I can't help but think this means the Autobots and Crescendolls will eventually go up against each other...
Either that or they never meet.
