A month into the new Aviva Premiership season, and there are storylines aplenty at both ends of the season.
Maro Itoje's 31-game winning streak for club and country came to an end with Saracens defeat at the Stoop, while Bristol's troubling start continued with another disappointing home defeat.
Wasps claim fourth straight win with victory at Northampton
After losing at home to Bath on the opening weekend, pressure was on the Northampton Saints to get back to winning ways at their Franklin's Gardens stronghold.
Unfortunately for Jim Mallinder's side, they ran into a rampant Wasps side who have now won all four of their fixtures this season after this 20-15 triumph.
The hosts got off to a flyer, scoring inside two minutes through George North, but they soon found themselves on the back-foot thanks to an incredible piece of skill by Danny Cipriani. The fly-half, who was playing his 100th game for Wasps over two spells at the club, dribbled the ball through, before scooping up his own kick and passing to Guy Thompson who timed his offload to try-scorer Jimmy Gopperth to perfection.
Taking a 10-5 lead into the second-half, Wasps moved eight points clear before substitute Tom Kessell brought Saints back into the game after sniping his way over the line from close range.
That was as close as the home side got though, and a break from Dan Robson followed by a chip through was collected by Josh Bassett for the game winning try.
Quins claim surprise win over Saracens
What looked like an all-conquering Saracens team were defeated in their first London-derby of the season, losing 17-10 to Harlequins at the Stoop.
Tim Visser's early interception gave Quins the perfect start as they flew out into a 10-0 lead in the early stages.
That lead opened out even more before half-time, with Charlie Walker crossing in the corner following excellent build-up play which involved both Tim Swiel and Mike Brown.
As expected, Saracens roared back after the break, but the 17-point deficit proved too much to overturn, with Richard Wigglesworth's try meaning they left with just a losing bonus-point.
On Sunday, Leicester extended their unbeaten home run against rivals Bath to a 14th season with a 34-14 win at Welford Road. Brendon O'Connor, Ed Slater and Tom Youngs were the try scorers for Leicester, with Semesa Rokoduguni and Tom Dunn crossing for the previous league leaders.
Bristol endure tough weekend with relegation rivals impressing
After finally making their return to the Premiership, Bristol look to be up against it if they are to maintain their place at England's top table going forward.
Andy Robinson's side came up against a far superior Exeter Chiefs side on Friday evening, and were brushed away 41-17 at Ashton Gate. Olly Woodburn and Thomas Waldrom each scored try braces for the Chiefs, with Sam Hill adding the pick of the tries late on.
For Bristol, Jordan Williams, Ross McMillan and Max Crumpton scored tries, and for the third time this season, Bristol fell one five-pointer short of securing a much-needed bonus point.
More worryingly for the new boys, is that the other favourites for relegation both had promising weekends. Newcastle secured their second win of the season, beating Gloucester 18-13 at Kingsholm thanks to tries from Dominic Waldouck and Alex Tait.
Meanwhile, at Sixways, Worcester finished level for the second time this season, drawing 34-34 with Sale in an enthralling encounter. Two scores in the opening 20 minutes from Will Addison gave Sale a 17-3 lead, before the home side hit back with four unanswered tries to lead 31-17, with Jonny Arr, Perry Humphreys, Wynand Olivier and Jamie Shillock each crossing.
An AJ MacGinty penalty got Sale back into contention, with a pair of tries from front row duo Neil Briggs and Halani 'Aulika in the final 15 minutes helping the Sharks to secure the draw.
