Is This a Threat?

From a distance, Theodore looked at Noah, who was smiling at him. He felt something strange about that person; he did not usually take the initiative to meet him. Moreover, Theodore knew very well that Noah didn't like him at all. 

"How strange that he called me," Theodore muttered in confusion. 

"Do you know him?" Geoffrey, who saw Theodore's reaction, was not too happy with Noah's call. He also guessed that the person was not too close to Theodore. 

"I know him. You can go first; I'll catch up with you later," Theodore replied as he told Geoffrey to leave first. 

Since Theodore had told him that, Geoffrey nodded his head and started walking away from Theodore, who started walking in the direction of Noah. 

Before turning the corner, Geoffrey glanced in the direction of Theodore and Noah, who seemed to be talking at the moment. When he saw Noah before, Geoffrey felt like he had seen that person before, but he forgot where.
