Well, I was sorta expecting those two to snuff it - I'd heard before that Tosh and Owen were probably not going to be in season 3, but I was hoping that (and the other rumours about s3) was wrong. Still, there really wasn't anything much more that could be done with Owen to be fair. The ever increasing amount of unhealable injuries that he would get would eventually mount up unless they found a magical healing
Tosh I will miss a lot more than Owen to be fair. I was hoping that as her 5 years of working for Torchwood were up, that she'd get to retire for a bit after Owen's death. *sigh*
Overall, Jack was a complete idiot. You're in Torchwood 1901 and now have 107 years to plan. Anything you think up would be something better than he came up with. At the very least, set the defrost to go off a day before this all happened - maybe manage to sneakily get all the bomb sites evacuated? Sheeesh... and I refuse to believe that no-one ever looked inside that drawer for the last 107 years and went "Hey, isn't that Jack?". Even Tommy got yearly checks.
RIP Tosh - you will be missed.
Owen? Shut the door on your way out.
