And my motives used to be so pure.

[So, this is Castiel. The face is definitely Castiel's, at least. That expression - probably mostly aptly described as 'just woke up and what day is it?' - is not characteristic of the angel. Additionally, there's the fidgeting, the looking around, general confusion. He's a bit away from the barge, trying to get his bearings. Also, while the voice might sound a bit like Castiel's, it has new and exciting things like tone and inflection!]

How long ago did Shendu try to take over the barge, and where the hell is this?

[Castiel is in the greenhouse.]

The demon Shendu has been smote and cast to oblivion; he won't bother this ship any longer, nor his host. I hope any sustained injuries have been taken care of. Thank you, jailor, for feeding my vessel while it hungered. And to Eddie and his associate, for freeing me from that cell. Its power was suffocating.

Does the cafeteria serve hamburgers and.. [he pauses, considering the the words] "root beer"?

All I know about you is your negligence and great strength, but I see no harm in requesting a number of. I can pick up a tree or bush of any size, weight or height and any place on this ship, so that won't be a concern. I suppose you'll probably ignore this. I won't be offended.

[Castiel details a lengthy list of plants that require all kinds of habitats and climates, from your classic chrysanthemum and wildflowers to venus fly traps, massive redwoods and parasitic vines. He knows all of their scientific names, of course. He's shooting for the moon here.]

[PRIVATE to ARTHAS]

You're no demon. Are you one of purgatory's children?

[PRIVATE to HOFFMAN and BUFFY]

I politely request you not banish me.
