I did go for the cliche of Remus staring at Sirius's "silver orbs"-- only to follow it up by mentioning that Sirius was carrying a basketful of "silver orbs" that they'd transfigured in lessons for something-- but I decided to keep the Mary Sue cliches with the two Mary Sues.

As for the sequel, I'd consider writing it, but given my track record lately, I'd probably never finish it. (At the moment, my computer may be storing more unfinished stories than finished ones.)
