The sigh of relief was audible as Grantaire's words sunk in. He couldn't imagine not spending the most important day of his life with his best friend. He had a family here and he wanted them around. All of them. "I'm glad," he said quietly, smiling slightly. "I just... I don't want to hurt you. That's never been my intent, not through any of this." He'd already cost him his life. That was more than enough.
"Even if you do only want to come to mock me." He refused though. There would be nothing foolish said because he was not going to risk ruining that day for anything. If nothing else, Eponine deserved a perfect day and he intended to see that she get it.
His expression darkened a bit at the apology but he only shrugged. "I know that wasn't what you meant. I know it wasn't some slight against me. But I do worry. You can't keep running, Grantaire. I'll keep fighting for you, because I won't lose you again, but in the end it's up to you. It's your choice." Which was hard for him. Enjolras didn't like giving up control. But he understood that he didn't get the final say. Short of locking him up as people seemed to think he was, there was nothing he could do but keep being supportive.
