GWS are about to show how well they've learned some harsh AFL lessons, a fortnight after they were dismantled at the MCG.
The third-placed Giants will deservedly start warm favourites on Sunday against Melbourne, who are 15th.
But the Demons' encouraging month and Giants' abysmal MCG record make this an important game for the two teams.
If Melbourne can reproduce the best of their last four games, they are every chance of a major upset that can put their season back on track.
GWS are doing plenty right, but only managed five goals on May 12 when Hawthorn's Alastair Clarkson put on a coaching masterclass.
It left his former assistant Leon Cameron bemoaning the Giants' poor mentality and calling the loss their worst performance for some time.
The Giants have won at the MCG only twice in 16 games.
Even allowing for their lowly start, it is a horrible record.
"If there's anything in it, I hope we find it, because we know they're a quality outfit and probably one of the premiership contenders," said Demons assistant coach Troy Chaplin.
"The boys are looking forward to it ... and we're back on our home deck."
The Demons feel they are building after their poor start to the season.
There were some encouraging signs in the Anzac Eve loss to Richmond, followed by two narrow wins.
They were right with West Coast last weekend until the last quarter, when the Eagles snuffed them out.
Scoring remains a major issue for the Demons - they are only averaging 70 points a game, but Chaplin said that will come.
Crucially, their defence and contest are much stronger than the early rounds, when they were deplorable.
"The last three weeks, we've started to see our game come back into some really good shape," Chaplin said.
'"Obviously last weekend was disappointing - we were right in the game until the last five minutes, obviously against a good team.
"The areas of the game that we really felt we needed to fix up, we've started to see improvements in that."
Melbourne also have suffered from a bad run of injuries, but the youngsters who have come into the senior side have proved unlikely bonuses.
"We've played guys who potentially may not have had an opportunity if (injured) players were fit," Chaplin said.
'"We've been able to see the likes of Marty Hore, Harrison Petty, Oskar Baker, Jay Lockhart."
All four of those newcomers will play against GWS.
