Thordarson's team's victory at York Street ended the Pilgrims' 10-game unbeaten record on home soil and, more importantly, took that smug grin off of manager Steve Evans' face.
But the Magpies will be hoping that they can end a sequence of their own tomorrow, that being their two month, five-game winless streak at Meadow Lane.
Tomorrow's game, though, presents something of an oppurtunity for the players to get this unwanted monkey off their backs.
Tipped heavilly for promotion after being relegated from League One on goal-difference, Torquay currently lie at the very foot of the League Two table, having endured a miserable return to football's basement division.
Following their 0-0 draw with the Magpies on the opening day, Leroy Rosenior's team have managed to chalk-up just three league victories, with just one of those coming on their travels.
In total, tomorrow's opposition have lost 8 of their 10 league games on the road this season.
Rosenior has come in for increasing criticism from irate Seagulls fans who are beginning to fear that an unlikely double-relegation could be on the cards.
Thordarson (below right) will be hoping, inadvertently of course, to compound their misery tomorrow.
One advantage the Magpies will have is that the Meadow Lane atmosphere should be far more positive than the last time they took to the field on home soil against Cheltenham two weeks ago.
This should, hopefully, mean a chance for positivity around the 'Lane, with the arrival of two new players in the form of Liam Needham and Mark DeBolla set to add to the good mood.
Chesterfield striker DeBolla was signed on a six-week loan from the Spirites and is likely to make his debut as a substitute tomorrow. A man who came through the ranks at Aston Villa and was then signed by Charlton Atheltic, he is a player of some potential.
Attack-minded midfielder Needham, meanwhile, comes on a non-contract basis from non-league and won't feature tomorrow, due to the step-up in fitness from part-time to professional football.
Thordarson has already named his preliminary squad of 16 for tomorrow's game, with Matthew Gill, Chris Palmer and Matty Williams all missing out. Steve Scoffham continues to recover from a broken cheekbone.
Brian O'Callaghan may keep his place in midfield after a good showing at Boston last week, but Thordarson may opt for a more attacking option in Stacy Long, depending on the Icelandic's mind-set.
Notts (possible): Pilkington; Tann, Baudet, Wilson; Pipe, O'Callaghan, Edwards, McMahon, Ullathorne; Hurst, White.
Subs: Marshall, Friars, Long, Sheridan, DeBolla.
