India's lead was 244 when play resumed under cloudy skies with the floodlights on. Brydon Carse began with a good spell and, having seen one edge fly through the slips, eventually nicked off Karun Nair for 26.
But that only brought in Gill, who is in the form of his life.
Admittedly England were tired and the situation free of any pressure after he got himself in, but he batted in similarly controlled fashion to his epic 269 in the first innings.
When KL Rahul had his middle stump uprooted by Josh Tongue, Gill was joined by Pant who played extraordinary scoops and cuts with the ball, and his bat, flying to all parts.
Crawley dropped Pant when the left-hander drilled to mid-on on 11 but it may not have mattered. India were already 321 ahead.
On 31 he swung so hard the bat flew from his hand. The same happened on 65 and, while the bat landed at mid-wicket, the ball ended up in the hands of long-off.
Throughout it all, Gill remained serene, adding a further 175 with Jadeja. He hardly offered a chance, reached his third hundred of the tour in 129 deliveries and his 150 by hitting a towering leg-side six.
Gill has 585 across two matches in the series, his first two Tests as skipper. On Sunday he may well have his first victory as India's Test captain.
