Quick thing, I don't own power rangers although I wish I did because Dana/Carter scenes would be a LOT better.
Anyway this is my attempt at fixing them and making their past a little deeper.
~episode 9: Go volcanic~
Carter was worried when Dana told him where she was going. He wanted to go with her but the others were enjoying their hot dogs, "Dana, I'll meet you in town." Carter replies getting up and walking away he hears Dana laugh "Ok, see you there." Dana knew there was no escaping from him.
They both sat at the bus stop together as the bus arrived they both got on, they noticed the guy dressed in all black stuff money into his duffel bag "That's suspicious." Dana whispers, "I agree," Carter put his arms around Dana protectively.
They both looked out the window as the robber pulled out a g*n, as the worked together they got the robbed in hand cuffs they carried around with them making this a victory. They made it to the mountains safely and told the robber very motivational things then went away to the volcano.
Carter and Dana were there when the demon was summoned so they were the ones who destroyed it, the others came with the rescue rover, as they defeated the demon it didn't rise,
"Carter, blast the remains." Dana whispers in his ear. He did as she said.
At the end of the episode the robber realised what he did was wrong and apologised to everybody on the bus, he was taken away.
Carter and Dana went back to the volcano as the others went away on the rover. Carter then proposed to her and she accepted, making them both wear rings.
