Watch what happens next.

I watched in rapt attention as the next minute passed, everything happening in slow motion and all too fast at the same time.
Eva, still stunned by Samuel's obviously forceful approach, found herself at a loss for words as she stammered and looked at him with wide eyes.

And Yara approached, a cunning fox seeing her opportunity to move in and get what she planned on having all along.
She got there, and grabbed Samuel by the shoulder, turning him around.
She said something, something that made an effect on both the persons standing there, putting joy on Eva's face and confusion on Samuel's. And she led Samuel away. More like shooed him, before turning her attention towards Eva, talking to her.

Samuel approached my position, and spoke to me:
"That bitch Yara got in between."
"That was the plan." I told him, smiling at him.
"Oh you sly one." He thought for a short moment. "Damn that's a good plan. Does it actually work?"
"See for yourself." I said, pointing to my two friends, as Yara hooked her hand behind the other's back and led her away, deeper into the school.
"Tight. Might have to use that tactic someday." He announced, before walking away. "You owe me one!"
