Bringing an unaired task back up
As tarfly said, no teams were shown reading the Pit Stop clue in Leg 2, so we're guessing there was a RB after it
Now I do remember Ross & Tarryn and Adam & Dane trying to get a train to the Pit Stop, and after rewatching the episode, they were trying to get a train from OLD DELHI RAILWAY STATION
Now if you look at the distance from the Bollywood task to Old Delhi, you will wonder why the hell those teams went FURTHER AWAY from the Pit Stop to get to the Pit Stop. My best guess is that the RB was somewhere in Old Delhi
Joseph & Grace and Lucy & Emilia were also shown running around looking for a auto-rickshaw to take them to the Pit Stop. They were definitely running around Old Delhi, I recognised it straight away
This could also explain Shane and Andrew going from last at the Bollywood task to 7th at the Pit Stop.
After re-thinking it, there was probably a RB in Old Delhi, which was probably some pointless task the editors thought they would cut out
