I think they bonded with each other well. staying in Bigg boss house can be tough sometimes. Everyone needs some one. They are just building friendship. I dont see any sparks flying between them. I think that massage that kushal-Gauhar and Tanisha-Arman gave each other last year left us all in a shock. so we are measuring these two based on last season events.
For now I am thinking it is not too serious.
I also am impressed how Diandra took so sportively when she was called least beautiful.
However, I am not sure about Gautam's prespective. But I am sure if he crosses his limits, then Diandra will put him in his place. For now (just watching 3 episodes) it looks like a growing friendship and friendship only.
Maybe down the lane it might change. I am not sure. So I may change my opinion then.
for now, their holding hands also looked sweet in a funny way.
