Talk about Badgerpaw please! He's my favorite. Also, how's Wrenwhisker coping with Gorsepaw's death?
Badgerpaw doesn't make much of an appearance in the next book, so I feel a little more comfortable talking about him!
Rainpath is incredibly pleased with his little cousin, because that kid is the best apprentice you could start with - he's talented, he's well-behaved, and he's ambitious to do his very best at everything. He can be a little shy, sure, but never let it be said that he's a coward. He just needs a second to gain some confidence!
You can probably guess what his suffix will be, if you know canon. He definitely earned that one. Appropriate to ShadowClan culture, he found himself something to dedicate his life to. That happened to be, simply, being the best warrior he could be. And he nailed it!
As for Wrenwhisker... he's done his grieving by the time RSR starts. He still remembers Gorsepaw's tattered body very clearly, but it doesn't make him shiver every time he thinks about it. He's got new stuff to focus on, and he's going to worry about that now.
