Lance gets infected by a bug that entered his body during the last mission. He didn’t notice at first, but a few days later he started having nightmares.
He figured having a few nightmares while fighting an intergalactic war was normal, so he didn’t bother bringing it up to the team.
As the days go by his nightmares get worse and worse to where he’s afraid to sleep at night. Blue keeps telling him to talk to the others, but he doesn’t want to bother them with something they can’t really help with.
It gets so bad one night that blue asks the other lions for help. With their help she sent Lance’s dreams through the lions connection and the lions sent Lance’s dreams to their individual Paladins.
The next morning the Paladins all met at breakfast early to discuss how to help Lance but when he didn’t show up for breakfast they got worried.
When they went to go check on him they found him still asleep in bed, covered in sweat, and wrestling the sheets. No matter how hard they tried to wake him they couldn’t.
They call for Allura and Coran and they immediately know what’s wrong and take Lance to the medical bay, claiming they needed to surgically remove the parasite before it’s too late.
