@Jo - I wont agree that Rudr is someone who is only attracted to Gauri's physical appearance and not her mental beauty. He has never noticed her as a girl before but he knows her inside out, from the way he explained the real Gauri to Champu. Think he is aware of her mental beauty already, he just realized about her physical beauty in todays episode.
but rach.. Rudr never explained the Real Gauri.. he explained the Gauri who was thr for him & all the things she has done for him...
Champu described the real Gauri, one who struggles daily with life, loves everyone & can do anything for a friend..
Champu described G as a person & her struggles in life while Rudra could only explain the things Gauri has done for him....
n even if R realised G's physical beauty... it doesnt give him the excuse to check gauri out the way he did... in reality, a friend checking u out would most prob end with a sentence, said at a distance,
