D'athe nosed around the library, warbling softly to himself as he peered at the books, looking for something interesting. He pricked his ears up, falling silent as he heard a noise he didn't recognize, scrampering towards it, poking his head around a shelf to watch a blue box appear.
Weirdy box!
He scrambled up onto the top of a shelf, ignoring the fact he was putting gouges into the wood, watching from the vantage point as two men came out. One who smelled a bit like Jack, and he relaxed, warbling a cheerful greeting.
Jack! Who's your friend? He smells strange, not like anything I've met before. He scrambled down, pausing as he reached the floor again, tilting his head, ears pricked forward. You don't look like the Jack I met when I came here through the weirdy doorway. Not quite. Eyes too young.
