Sister [17f] went from promiscuous to extremely Christian in a matter of months. I don't know if this is normal or healthy?

I'm 23m.

Around mid last year, my sister had a pregnancy scare. There was a lot of shouting and discussions and drama with our parents.

In the end, she wasn't pregnant but was still heavily grounded and has basically been on curfew ever since. It's been loosening up a bit over the past months but still strict.

In that time, she turned into a Christian and is now frequently talking about waiting till marriage, honoring her body, staying away from sin, things like that.

She has a friend that is also very Christian and they sometimes go out with the explicit intention of ripping out little stickers some people leave in trees, walls and dumpsters, with phone numbers to some sort of sex chat. A lot of people do this, I've seen them before.

She got mad at me the first time she prayed before eating because she didn't tell anyone anything about suddenly being Christian. one day she just started praying and got mad at me for thinking she was joking.

In general, I'd say developing religion is not the worst thing she could have done, but to me, she seems to have gone from one extreme to the other with nothing in between.

Mom and dad are mostly pleased that she's honoring the curfews and is better behaved now. It's not like she was a drug addict before, but she was kinda wild and admitted to having had unprotected sex several times in the middle of the pregnancy drama.

I admire that she's found some structure to guide her improvement, and her Christian friend is generally a good girl as far as I can see, so they seem to be sharing good things in general.

I'm just wondering if it's odd/bad/weird/unhealthy to suddenly go to religion after something like this and get kinda defensive about it?

To be clear I haven't mocked her, but it took me a few days to realize that she was in fact serious about turning Christian, and she was hurt/annoyed about it, so we clashed a few times.

Am I overthinking this or is it a legitimate concern?

tl;dr: Sister went from partying and being promiscuous to modest Christian in a few months. Is this change normal and/or healthy?
