There was an anticipation that the Hornets might kick on and establish a vice-like grip on proceedings thereafter, but you can forget that in this league and at this ground, especially if you remember that ding-dong in the FA Cup here a couple of seasons ago.
QPR were in no mood to play second fiddle or be cowered by falling behind inside 270 seconds. Craig Cathcart, captain in the absence of his mate Tom Cleverley, made a wonderful sliding interception to cut out a dangerous cross from Bright Osayi-Samuel; Capoue headed one off the line; Yoann Barbet had Ben Foster scrambling across his line with a free-kick from distance that dipped and swerved all over the place; Foster denied Dominic Ball, the former Watford Academy player, from close range and then Macauley Bonne should really have steered a far-post header on target when largely unmarked.
It wasn't all QPR. Far, far from it. In between times and, as a result of various counter-attacks, Andre Gray headed instinctively wide from a Kiko Femenía cross; Troost-Ekong headed past the post from an uncannily similar position to the one he thumped in against Coventry City; Ismaïla Sarr had an effort he slammed at goal blocked; QPR 'keeper Seny Dieng made a finger-tip save to deny Gray and then Sarr, for a player of his rich quality, should have scored after being sent clear down the inside right channel.
