Seeing Pratik's performance in last episode made me finally say...

Abe sabko pata hain ki tu Simba aur Neha mein se Neha ko hi choose karega, kyunki abhi bhi usko dekh kar teri tharak jaag uthti hain. Along with that he can be in good books of Shamita by choosing Neha and there is a scope of a love angle again in future with her.
Toh phir kis baat ka itna drama kar raha hain?
Simba ko koi farak nahi pad raha tha toh tujhe kyun pad raha hain?
Aur tu akela nahi nikal raha hain Simba ko. Saare top 5 mil kar nikal rahe hain because they didn't save Simba, not just you.
Pratik purposely went in the last to make it seem like the game is in his hands (along with showing his poor acting skills), when from the beginning it was clear who he was going to save.
Poore episode mein drama kiya isne to make it seem like his choice would be unpredictable when it was predictable from the get go!
