Thank you! No, there is no allusion to any Silmaril. There is, however, an allusion to Maedhros' slight condescension towards his brothers, particularly Maglor. More than once he has gone against their good advice and gotten everyone into a sticky situation, and has kept quiet when he should have put his foot down. But that comes as part-and-pacrcel of being the eldest, so I don't blame him :)
