The Ghanaian midfielder was a second half substitute in Hearts' 2-0 win at Hamilton to the delight of new boss Jim Jefferies.
Kingston fell out with previous manager Laszlo Csaba and endure abuse from the Hearts boo boys.
But Laszlo is gone and Jefferies is delighted to have Kingson back even though he insist a how well he does will depend on how much he wants it as a player.
"After the second goal we put him on for an extra man in midfield. He has to use the time between now and the end of the season to show he can win the fans. I will be kicking his backside in training to make sure he is," Jefferies said.
Kingson's return would have delighted his national team boss too Milovan Rajevac who has seen his bad luck with injuries to key players get better lately.
Michael Essien has been tipped to make an earlier than expected return from injury while John Mensah came through 90 minutes for Sunderland against Arsenal after his horror run of injuries.
