Two timer
When Emily got restaurant, it did not take long for her to see Samuel. He had been paying attention to the door so once he saw her walking in he immediately raises his hand to her her attention.
His movement did not only get her attention but even Eric who was eating at the side saw him. He looked over and unconsciously and was surprised to see Emily walking over. She had told him she wanted to have her dinner inside her room, now she came over to the restaurant.
He was jealous, he knew that it was possible that there was something going on between her and Samuel but she had let him kiss her twice.
On those two occasions Eric seemed to have taken the inattentive but If Emily did not want that kiss it should not have happened. She could blame the first time on alcohol but what about the second time. Eric knew how sensitive Emily was.
