"You don't need my help?"

Dwayne's head bobbed up and down.

He guarded the laptop as if his life depended on it.

Clearly determined not to let Raven sneak a peek. Which was useless because Raven had seen it earlier. 

Raven stared at Dwayne's face and narrowed his eyes. His demeanor was still the same. His ice cold grey eyes, his expressionless face... But Dwayne can feel that Raven is waiting. 

Waiting for him to come over and show him what he was having difficulty dealing with.

Raven wanted Dwayne not to refuse him, but to rely on him. So he stood there and stayed silent. Waiting for Dwayne to retract back what he decided on and ask him how to do it.

But Dwayne did not back down. He step backward and darted to the opposite sofa, deciding to continue working on his assignment. 

Raven can only chuckle and said, "If there is a topic you don't understand, just ask."
