Indiscipline again threatened to undermine Eddie Jones' England against Wales, but their capacity to thrill was also on display. Following pre-match consternation over the fitness of Wales fly-half Dan Biggar – head coach Wayne Pivac and assistant Sam Warburton having offered mixed messages with regards to his knee complaint – Tom Curry and Manu Tuilagi decided to seek their own diagnosis.
Biggar gathered Ben Youngs' teasing kick in the second minute, only to see a white-clad freight train hurtling towards him. Curry, as was generally the case on a full-throated late afternoon in London, got there first, splattering Wales' number 10, with Tuilagi alongside to provided added, if largely unnecessary, muscle.
England's expert meshing of brains and brawn set them apart in the opening exchanges – Maro Itoje striding imperiously through the midfield before soaring to collect the subsequent line-out. Wales were drawn in, Curry did not miss a beat with the reverse pass and the returning Anthony Watson darted over for the first try.
There were plenty more instances where this undulating 33-30 win for Eddie Jones' men looked exactly as you might expect – one side tweaking and seeking to progress again having fallen agonisingly short of their World Cup goal, with their visitors in the early and often fumbling throes of transition.
Particularly in their defensive set-piece work, Pivac's men appeared a team breaking in uncomfortably new shoes; the glorious dances of a dozen years under Warren Gatland already feeling consigned to a fading era.
Wales' chances invariably came when an England team in a rush trod on their own jet heels.
This was never more evident than in the back-to-back passages of play that saw a swaggering 20-6 lead collapse to 20-16 either side of half-time.
Despite the clock having already ticked past 40, England sought to fizz the ball through hands on halfway where Tuilagi erred and Itoje was pinged for a high tackle on Biggar. Equilibrium long restored from that early pasting, he bisected the posts.
Then, 27 seconds and a lackadaisical restart later, Twickenham was aghast as Justin Tipuric gleefully scampered over.
Now was the time for Wales to open up some old wounds. England led 10-3 at half-time in this fixture a year ago, before unravelling and losing 21-13 in a fug of antagonised indiscipline.
If captain Owen Farrell intended to help his men turn over a new leaf, scrapping with George North and putting in a high tackle on Josh Navidi for Leigh Halfpenny to slot a pair of first-half penalties did not exactly amount to leading by example.
But from the tee, Farrell was typically unerring with six from six, and his combination with George Ford for Elliot Daly's 32nd-minute score meant Joe Marler's peculiar method of introducing himself to Alun Wyn Jones was arguably not England's most notable ball-in-hand moment of the match.
Those flashes of finely grooved, frictionless quality are the preserve of teams perfectly in sync with their wider strategies. Pivac's Wales cannot expect to be at that stage of realisation, although their unflinching spirit until the last bodes well for the journey ahead.
Tuilagi went over for another glorious try after more brilliant work from Youngs and Ford, although the bulldozing centre underlined England's remaining appetite for self-destruction with a late red card tackle on North. Biggar and Tipuric's late tries consequently came against 13-man opposition, given Ellis Genge was already ensconced in the sin bin.
Triple Crown secured, Eddie Jones' England don't look likely to stop playing on the edge any time soon, where the falls can be needlessly damaging but the views are often indisputably spectacular.
