Thoughts and questions about Angel S1

[chicken]

After re-watching "Five by Five" and "Sanctuary" and thinking more about the Faith situation, I have these questions:

1.) I've got to be the first Slayer in history sponsored by a vampire.

I haven't seen seasons two or three -- does Angel ever visit Faith in prison? Does she ever get any visits or letters or help from Angel or anyone, or is this her own struggle by herself? Because clearly by the point in S4 when Wesley breaks her out, she seems to have changed a bit, and I'm wondering exactly how that happened. How does she find peace with her past and change her attitude about life?

2.) Now, post S7, does she feel she owes society and herself any more time -- does she feel the need to check herself back into prison? If not, then when some authorities happen upon her, will they try to make her go back (unsuccessfully no doubt)? Or will there be a kind of trial thingy where maybe a bunch of potentials (well now they are slayers) might testify on her behalf, like "hey, she helped us, she saved some of our lives, she's redeemed, please say she's out for good now, or at least on parole" type of thing?

3.) I kind of get the feeling Faith is a lot like Buffy (whether redeemed fully or not), insofar as both are still unbaked cookie dough. So she won't be *seriously* dating Wood or anyone else, not for a while. Does this assumption seem right?

4.) Out of nowhere, a question having nothing to do with Faith, but it has been bothering me because "Welcome To The Hellmouth/Harvest" were on FX today:

Why do some vampires never seem to get out of game face? For example, I don't think we ever see Luke or the Master have regular face, they seem to be in game face all the time. Along similar lines, when and why is game face voluntary and when is it not? In "Tabula Rasa" it seemed involuntary for Spike, and he did not even know he was in it, or that he was a vamp. A lot of times with Angel, game face seems like an involuntary state brought on by negative stimulus like the way the cut he got in the gladiator ring in "The Ring" seemed to force him into game mode/face (like Oz on the table in the Initiative or smelling Willow on Tara and getting upset). But other times it seems totally voluntary, in fact, most of the time.
