Yes. Grim could have admitted that he was a little jealous of Yuyui.
Grim had seen Yuyui at her worst, when she had been about to leave Skullius' Faction back then. They were still a combat force of the Severed Union that time. She had thought she didn't have what it took to be a combat expert, much less someone who could be useful to Skullius.
She had even stagnated for a while, dawdling around while the others had been sharpening themselves as fighters.
But suddenly, when it mattered the most, she even managed to save them all from Jerthrax, the Vision of Misery during the voyage across the Central Boundary.
How?
Well, Yuyui had told Grim. She had reconciled with her past and it became a part of her core strength, especially when matched with her present circumstances and the future she hoped for.
This had begun to nag the Unlimited Star.
