I see a lot of comments on DDT about Eijaz :D
TBH even I am feeling bad for him these days. His enthusiasm has gone down, he feels lonely, no friends. Upar se not getting proper footage in episodes.
But IMO whenever Eijaz has been given favorable circumstances in the game, he has gone berserk and overconfident. When he was made the captain he became obsessed, was forming a great bond with Pavitra, Rahul V, Nikki, Jaan but saved Jasmin to prove I-don't-know-what (saving her never helped him in the game!) and that alliance never took off. During the angel-devil task he went crazy. When he won the immunity stone and his body language became overconfident, was taking on Rahul V and Jas without holding back. But he fears taking on Jasmin now that Aly is back! This is disappointing. Then when he thought his game is going fine after alliance with new challengers, he was flying high. Suddenly making absurd statements, going all out in tasks.
Due to his past experiences, he needs constant validation and assurance which he seeks from wrong people, like here mostly from Aly and Rubina. In the process, he gets annoyed by whoever tries to get close to him and does not value them. I don't blame him but honestly he has distanced himself from people.
