Sunstorm: *treats Red Alert with the up most kindness and respect, calmly respects her judgement of when it is and isn't safe to visit each other even if it isn't convenient for him, and makes sure his siblings and fellow cons are also respectful when they meet her*
Red Alert: Y'know, it sure says a lot when a Decepticon respects me more than the fucking Magnus of Cybertron.
Red Alert: *gives Sunstorm a kiss on the cheek*
Sunstorm: *covering his smiling, blushing face* Oh gosh!
Red Alert: *soft chuckle*
Red Alert, internally: He's too pure!!! I love him so much I can't believe it!!! Why the fuck isn't he on my side so I can marry him right now!?!?
