Asim is just being insecure. Neither Aarti nor Sana have given a real reason for him to be insecure. In a task, if there was a choice between Asim and any other guy besides Sid, who would Sana or Aarti choose? Would Sana choose Paras over Asim? Never. She has always said that she knows nobody will be for her, but she will play for the team. People’s issues are only because she socializes and loves to laugh and have masti. She can’t stand the negative vibes and chillam chilli 24/7. But if she can’t be considered trustworthy because she can’t keep a gruff face and stop talking to everybody in the house, that’s his problem.
Same with Aarti. Her loyalties have always been firm. In fact she doesn’t even socialize much with everybody except a stray word here and there. Ofcourse Aarti has done her bit in asking Sid not to trust Asif or Sana at earlier points and Asif himself has asked Sid not to trust Sana. Never heard Sana ask Sid not to trust either. Asim’s hollering at the girls are not warranted.
Anyway, Asim’s current issues stems from Vishal’s entry. He feels the girls may swing away from Asif towards him. Needless insecurities. He just needed to maintain what he has/had. Both teams now need Vishal on their side and both Arhaan and Asim were scapegoated. To Arhan’s credit, he had more strength and skills and could cross the tunnel. Asim probably has claustrophobia or respiratory issues added to lesser strength compared to Arhaan and that’s okay, but to blame the girls is petty.
