CliffJumper met Arcee back before the war, falling in love with her at first sight. They eventually become partners a few days later. CliffJumper was talking with Smokescreen about how he wanted to make her his sparkmate. "I'm so nervous. What if she says no???" Smokescreen rolls his eyes, trying to calm down the nervous mech. "You've been together for a while now, I'm sure she's ready too." CliffJumper walks towards Arcee, who was speaking with Bumblebee. "Hey there, Cliff!" She plants a kiss on his cheek plate as CliffJumper holds her hand. "Arcee, may I ask you something...?" Arcee tilts her head confused, agreeing. "Sure, what is it?" CliffJumper takes a deep breath as he knees down. "Arcee, you're the most important bot to me in all my life. You make me feel so many things I can't describe when I'm with you. I want to spend the rest of my life with you. What I'm asking is..." He pulls out a ring towards her. "Will you be my sparkmate?" Arcee covers her mouth, holding her tears. "I will, Cliff." He puts the ring on her digit as they kissed passionately. "I love you, Arcee." "I love you too, Cliffy."
