The two of them continued to talk for a while waiting for the doctor's diagnosis. Since they were doing comprehensive tests, they ended up taking a bit longer. Lucas eventually couldn't hold on anymore and dozed off while still sitting next to Jen's bed.
She did not wake him up because she knew that if she suggested he sleep on the other bed in the room he will refuse and try to resist his fatigue. So she just calmly played with his hair as she waited for the doctors to come back with the test result.
Lucas was able to get another thirty minutes of sleep before he was woken up by the arrival of the doctors. He tiredly opened his bloodshot eyes and looked at the three doctors who had come into the room.
