between msn and host clubs

I was just readin' the wonderful story of host club, where tamaki finally understands, that he'S in love with haruhi, during a calm-no-one-say-something on msn, then suddenly Mr. Jack wrote me this mesage:

And so the black cat was watching the end of the world, thinking at
his past, when he had time and didn't do anything usefull ...

what did he mean with it?
