There is nothing better for an away supporter that beats a last minute winner, and one that comes two minutes into stoppage time is a particular delight.
When it's one of the quality that Francis Laurent scored at Brighton Saturday, you have one to savour for a very long time.
Sadly, the Blues defensive vulnerability that we thought may have been checked with M'Voto and Barrett's growing partnership returned to haunt them, though the Frenchman was reported as having a hip problem which caused him to go off.
Luckily, Brighton's defence was worse.
And when three of your central strikers all score leading to a win away from home, Tilly was obviously the happier of the two managers.
That attacking weapon, sometimes we seem to rely on it too much, of a whipped in cross from the right, we won't mention his day job of defending, led to both Southend's opening goals.
While poor defending of Nick Forster, of all people in his current run of, now, seven goals in five games, and he had another one here disallowed for offside, meant the sides went in level at half time, the way it seemed for most of the second half it would end.
Blues boss Steve Tilson decided to start with Sunderland loanee striker Roy O' Donovan, dropping Laurent to the bench, while making the opposite decision at left-back, starting with Johnny Herd, and allowing the loan signing from Wolves 24 hours before, George Friend, to get used to his new surroundings and starting as a sub.
After only 8 minutes, the good Lord Lee Barnard scored the first, and his eighth of the season, from about the first meaningful attack, getting down low to meet a Francis cross, who had linked well with O'Donovan. A marvelous looping header.
More midfield passing around then, from nothing, the ball than fell free on 21 minutes, after a route one clearance by home shot stopper Kuipers, for Nicky Forster, of all people, to shoot past Blues keeper Steve Mildenhall.
Again, more midfield passing around then, just six minutes later, a Moose corner, headed back across goal by Captain Adam, Kuipers flapping, Roy O'Donovan pounces on his debut and a big smile breaks out over the Cork boy's face.
When you've only scored once in over two years and had the injuries he's had, you'll take a tap-in!
We should hold on to that. No we can't.
Five minutes from the break, Jean Yves M'Voto was caught on the ball by Forster who was in like a flash, not bad for a 36-year-old, to make it 2-2.
The other loanee from Sunderland was obviously injured and replaced by Osei Sankofa, who went to right back, while Francis moved to centre half.
Jean-Francois Christophe then had a good chance in first half injury time but headed over from an accurate left wing cross from Herd.
So five chances, four goals!
With Herd going off the second of the week's loan signings, Wolverhampton's George Friend became the second Southend debutant of the match, a straight swap position wise, but we now also lost the second most attacking outlet for the Shrimpers, Johnny's long throws.
As both teams woke up to the fact they could actually win the game with their dodgy defences the game started to open up with first Southend winning a number of corners in succession, then Brighton.
Mildenhall making his now traditional great save low down from a Forster volley in the 58th minute.
Ten minutes later Elliott Bennett curled a shot against the bar from the edge of the box with Big Steve just a spectator, and from the ensuing melee Forster had the ball in the net but the assistant's flag was raised.
Gratefully, for everyone involved with the Essex club, Brighton boss Russell Slade took Forster off.
Tilly then played a trump card, not something he's known for, by taking off the tirering O Donovan with Francis Laurent.
The tall Frenchman picked up the ball in the centre of the Seagulls half, put his head down, ran into the box, twisting the Seagulls defender Elphick inside and out, and shot past Kuipers from a very sharp angle.
The travelling support went wild, they could at least see this goal clearly, they were also seeing Southend gain three points away from Roots Hall for the first time this season and into 8th place, a win away from the play-off zone.
