Science is Felicity's strongest subject, in which she excelled in, while Oliver excelled in English. They had the same classes on the same day.
Ms. Hildebrand, their chem teacher, had them working in pairs on a solution of iodine and chlorine. Felicity could see that Oliver was having some problems with his solution.
"Ms. Hildebrand, May I go over and help Oliver?" she asked.
Ms. Hildebrand gave a slight nod. She went over to him. Felcity explained that the solution was one part chlorine to two parts iodine. She took his hands in hers and moved them into the correct parts. After the solution was mixed correctly, Felicity looked down at Oliver's hand. He seemed to have burned it somehow.
Luckily for him, Felicity knew first aid to a certain extent. She took him into another room and tended to his injury.
"This might sting a little," she said while holding a bottle of rubbing alcohol.
She started pouring on the alcohol to his injury. He grimaced in pain. But after that initial sear of pain, the wound didn't hurt so much. She took a bandage and wrapped his hand.
"Thank you," he said. Then he kissed her on the cheek. She can feel herself blushing a deep shade of red, almost crimson in color. He saw this and could not help but snicker at her.
