If we want to imagine Rahim as villain or grey character, we can consider some points(apologies for wildest thoughts in advance
) :
- when everyone including Aimen was uncomfortable about the Kharaab mausam & decrease in temperature Rahim was smiling looking at the cloudy, dark sky! Usne kaha bhi Atiqa se, "kharaab kahaan hai, mujhe toh kaafi romantic mausam lag raha hai" 
- We have those gloves on him in the thumbnail! Jahangir, the servant who switched off Cctv when Rahim asked, only heard Rahim's order, not Shehroz or his friends! Even Afia didn't see Shehroz doing this, it was Rahim who told her Shehroz did all this!
- We see, everyone open their respective room using thumb impression! Without Rahim's knowledge how can Shehroz take Aimen to his room then, unless he kept it open? What if, the worst, it happened when Rahim was trying to explain Aimen Shehroz is his brother? And he Shehroz to believe he did that using his drugged state? 🫣🏃🏽♀️
- Also, in the beginning of the show, we see people seeing Aimen in injured state at seashore! And police coming there, we didn't see Rahim or his car in that scene! What if Rahim added himself in that scene to manipulate the situation for his benefit? And, if he was really nearby where Aimen was thrown, wouldn't the police have solid evidence against him, being in the crime scene? Wouldn't the pedestrians & police see him there?
- the Rahim who could reach on time to save Aimen from Shehroz's prank at pool side because he probably was observing Cctv & who questioned Aimen about Jamal the same way, would have already known Shehroz is messing with Aimen, from cctv footages! Maybe, he was waiting for Shehroz to push her into pool, to save her & appear a savior! And those cctv footages can help him paint Shehroz a villain, later on?
Okay Rahim can't be doing all this we know
🏃🏽♀️
How about Rahim getting Aimen fired after her question to Afia at orphanage went viral? So that she could join his hotel? Maybe impressed with the point she raised? 🫣
