Rahul seems more lost after returning to the house. He wanted to fight Rubina and Eijaz after returning because he said you should fight with whoever you consider strong. We saw he poked Eijaz for random things and tried to create a fuss.
But I guess he soon realized challengers are quite strong, so he should be against them instead. The problem is....if you operate in a large group, you automatically kinda lose. You blend in. You no longer look like an individual player who thinks on their own.
