After the bwitch officially left x42, chelsea and x were seen everywhere on the planet ... hugging, holding each other, etc. Of course a token gram'ma was tethered along, but the bond between chelsea and x42 was ... well ... in many eyes .... er, ... unnatural.

Chelsea's gotta' go and Klaus fits the bill.
(I don't know if a pun is intended in that last remark ... it just came out, made sense in an excrutiating way and I decided to let it stand)
