The penultimate month of the season saw perhaps the greatest mixture of emotions for Everton's players and fans.
Norwich City's Carrow Road had proved to be a tough ground for visiting teams over the campaign, but the Toffees were unlucky not to come away from the ground with all three points.
That man Jelavic produced two more one-touch finishes to twice snatch the lead either side of a strike from Johnny Howson.
The Canaries' own hitman Grant Holt was on hand to make it 2-2 late on, but the draw stretched Everton's run to just two defeats in 16 games.
Easter Monday brought smiles to Blue faces with a second comprehensive conquering of Sunderland.
David Moyes opted to rest several stars with one eye on the FA Cup semi-final, but his team produced a stunning second-half to run out 4-0 winners against the Wearsiders.
Magaye Gueye bagged his first Everton goal, before Steven Pienaar and Leon Osman produced near-identical strikes a minute apart.
Victor Anichebe completed the rout - although his effort was later attributed as a Jack Colback own goal.
The Blues really couldn't have gone into their Wembley showdown with rivals Liverpool in better shape.
Only Pienaar's ineligibility prevented a full-strength line-up and over 30,000 Evertonians went delirious when their new favourite Croatian continued to keep true to his promise of 'goals, goals and more goals'.
Midway through the first half, the former Rapid Vienna poacher was in the right place at the right time when Daniel Agger and Jamie Carragher hesistated in defence and the latters attempted clearance rebounded dangerously into the box off Tim Cahill.
Jelavic's cool finish in the big arena was not to be enough however, as Luis Suarez latched onto a undercooked backpass from Sylvain Distin and levelled from out of nowhere.
And, as the nerves set in, Andy Carroll headed home with just four minutes on the clock and Everton's FA Cup dream was over.
Many might have expected that to spell the end of the Blues' season too, few may even have predicted a walkover for table-toppers Manchester United when Moyes' men travelled to Old Trafford eight days later.
But Everton never give in.
Taking the lead through Jelavic, the Blues forced the Red Devils to respond through Wayne Rooney, Danny Welbeck and Luis Nani.
Marouane Fellaini then notched a spectacular volley, only for Rooney to net again moments later to make it 4-2.
Two goals down for a second time, that might have been that. Yet inside the last eight minutes, the determined Toffees provided another twist to an enthralling Premier League title race and pulled off a sensational 4-4 draw.
Firstly Jelavic swiped home with aplomb, before Pienaar sneaked in behind the Old Trafford defence and sent the away fans wild.
And the freescoring Blues would net another four goals for the third successive league game against Fulham.
A loud and buoyant Goodison Park roared for handball when Jelavic's free-kick struck an arm early on and the Croat gave goalkeeper Mark Schwarzer no chance with the resulting spot kick.
The Blues would ultimately go in at the interval three goals to the good, Fellaini's header making it two before Jelavic turned in from a tight angle after rounding Schwarzer.
The icing on the cake came on the hour mark when Cahill stretched to divert Pienaar's scooped pass into the net, putting a seventh-place finish firmly on the cards.
