Lovebirds Pickering: Tania, Michel, Yehia and bassma

The heated argument rose between Michel and Tania during gym class but no one knew why. All we know is that Tania was joking with Michel about a certain something however he became furious and threatened her to expose everything if the kept arguing on the same subject. What is this about and does it have to do with Tania's jealousy over Micho? On the other hand, Yehia became jealous because Ibrahim gave Bassma a bracelet, Yehia instructed Bassma not to accept the gift but she made it clear to him that she and Ibrahim are just friends and she considers him to be an older brother. She doesn't think she did anything wrong and she had already given a gift to Ibrahim which he liked very much. Bassma's mother also objected on her daughter's behaviors. Is this bracelet worth all this commotion and was it an admiration gesture from Ibrahim?
