I like DangerousAmber's idea. You should have an ultra-preachy one/drama filled one with the pastor, just to put a strain on the relationship. Obviously it's up to you what the effect would be, but, personally, I'd make the whole thing a bit sneakier. And then of course a shit bomb would explode when G's dad found out. Although, I wouldn't put that in for a while yet - let the relationship develop a bit first?
Also, you could have Frank accepting going back to school and living in with G and Mikey, like he was gonna be forced to at the beginning. Of course, now it has it's perks. ;) Anyway, have him go back to school and getting shit again, but Gerard helping him out? Could work.
That's all I really have at the moment, but the story is coming along great so far, so just continue and with any luck it'll stay up to standard. If I have anymore ideas I'll review again, and if you want anymore help, feel free to inbox me. This is a kick ass story, so it'd be a shame to see it end now. So, yeah, you want anymore ideas or anything, contact me. Or don't. I don't care AS LONG AS YOU CARRY ON THE STORY!!!
