Acting Weird

As Achilles walked closer toward Ryan and Tiffany, the two were still oblivious of his approach and chatting about something that he couldn't perceive, for some reason. After some consideration, he called out to the two of them:

"Hey! What are you two doing?"

The two jolted up in surprise by his call and they swiftly turned around. A hint of puzzlement and an unknown emotion were evident in their eyes. Ryan took a deep breath to calm himself down when he saw that it was Achilles who called. The man questioned in a dumbfounded voice:

"Oh, it's you, Achilles. Why are you here? I thought you were with the others?"

Achilles explained with his arms folded:

"I'm here to brief you about what we discussed. Why didn't you answer your call?"

Ryan seemed to be caught off guard for a moment, then he spoke in a stammering voice:

"O-oh!...Did you call me? I left my communicator in my room. Sorry."

Achilles frowned slightly.
