It is the same face he pulled after rolling the ball past Fraser Forster, the Irishman having been too timid to make a scene at Easter Road for fear that the assistant referee would raise his flag and make a fool of him.
His presence in a Hibs attack which has failed to score in just two matches since his arrival from Kilmarnock has been more eagerly celebrated by those round about him. Heffernan has scored three goals already and is expected to resume his role up front as his side front up to Aberdeen this afternoon aware that a victory would be enough to lift them over their visitors in the SPFL Premiership table and into fourth place.
Such a statement comprises a substantial rewrite from what had been scribbled about the Edinburgh side earlier in the season and the momentum fostered in recent games has allowed Hibs to move on from that uncomfortable episode early in the season. The sunnier disposition at the club is undiminished even when you shine a light on Heffernan's infraction.
"Maybe it shows that our luck is changing," said the striker. "The lads have said that in the games against Motherwell and Hearts earlier this season there was nothing in those games, but they lost by the odd goal in both. Now the team seems to be on the right side of that at those results at the moment. Hopefully we put in another good performance this week and get a bit of luck along the way."
Hibs were also accused of over-stepping the mark with some of their challenges following the draw with Celtic but they would not seem to be overly concerned. "Hopefully we put in the same committed performance as last week," added Heffernan.
It is the sort of sentiment Russell Anderson is able to grasp, especially now a "boxer's fracture" to his left hand has healed. Aberdeen's captain made his return in a victory over Dundee United last weekend and his presence and gutsy displays are likely to help embolden an Aberdeen squad which was tipped to achieve great things - or at least a top-half finish - at the start of the season, only to seem less impressive in recent outings. "There have been positives but there are still areas in which we need to improve," said Anderson. "We've been very difficult to beat, we've been hard to break down and we haven't conceded a lot of goals. The flip side to that is maybe we have not been creating as many chances as we were at the start of the season."
He is expected to be joined by Barry Robson and Willo Flood today and their presence could have a similarly positive effect on the Pittodrie side. "Hopefully that will bode well going into the next stage of the season."
