Since you're probably not going to get an answer from Dethklok, I'll tell you the status.
Ofdensen - Younger, punkish Toki - The same, but relieved because Skwisgaar - is apparently "the right age", about 30, (Younger Skwis, in case you're wondering) Elder Skwisgaar - Taking care of Miniver - Who is about 8 years old Pickles - Near as I can tell, he's 20
Teja - Hello. That's me. I haven't heard from Cassidy or Soren yet, but I can assume that they're just ignoring everything in lieu of their honeymoon. They probably don't know anything's going on yet.
Teague's fine, Lilo's fine, too, but she's the right age in my eyes, therefore probably a lot older for you.
