Ali didn't shake hands with PG :/

Did I miss something, or Ali did not shake hands with Pritam and Gautam when he entered the house. i thought I saw him going around shaking hands with everyone and introducing himself..He hugged Praneet and then I thought he will shake hands with Pritam and Gautam who were standing right there..But he called Puneet and hugged him, looking past Pritam I know he talked to Gautam on the way and said he wants to get as fit as him and then Pritam talked to him about the sleeping area..But they didn't get formally introduced in the beginning..no?

yeah i too noticed he didnt shake hands w/ pritam or gautam... guess he got distracted and wasn't intentional
