[To say he's been worried sick during that week would be... well, not really exaggerating a whole lot. Yeah, he had high hopes that Porthos would be back, but there's always the nagging sense that this time, it might not happen, and--
and even if it did, he might not come back the same. Might not remember.
This time, though, the "not come back the same" applies in a more literal sense.]
So... I'm guessing it's been more than a week for you?
[Great greeting, that, especially when it looks like Porthos hasn't even noticed him yet.]
