Your Aradia is great and I love playing with her! If you're concerned that events have caused a bit of voice washout, you could try what I always do and reread some of her pesterlogs. It's quicker than a full canon review and if you go to her page on MSPA Wiki, they provide links to all pesterlogs involving her, which is really handy! I've found it always helps me in the past, that getting the literal voice back on track really helps everything else fall into place.
