It wasn't fair to say the Doctor had been surprised that Jack's coup de gras had been his experience on Satelite 5. The Doctor inwardly winced. He'd seen the Daleks. He knew what those blasters of theirs did. He knew what they looked like, sounded like, and what they did. Daleks, he knew, exterminated.

Logan was curious how he knew. "Adamantium has this interesting frequency when it colides with something - especially if it scrapes against itself," the ringing, popping noise of those claws as they cut both his skin and locked into place let that ring go right into the Doctor's head.

He cracked open his journal and scowled. Ryuzaki. Back into his own little world a moment, feeling all patience leaving him.
