Specific fic that was Harry/Daphne (possibly Harry/Blaise). It featured a more sarcastic and witty Harry, but their interactions were started by what I think was a potions project they had to do together. It's all I remember of the fic, but now that I've thought of it I really want to look it over again, just to see if it was any good.

 

Wow uh... I think I know the one you're talking about. Search Harry/Daphne on FF.net and take the first ten results. Six of those will probably be what you're describing.

 

no, this is a harry/ fem!blaise one.

 

This but I'll be damned if I can remember the title.

 

Thanks, that helped. It's Inquiring Minds on ff.net.

 

I just found the one I was thinking of, took me a few minutes.

It took some skimming to confirm it, and the end of chapter 4 is what I remember about it.
