When Does Donna become a real person?

For all you 90210 lovers out there, you are well aware that Tori Spelling's character, Donna Martin, has ZERO personality for the whole first season.  She pretty much just stands behind Kelly and Brenda listening to them talk, and when she does add to the conversation, you just want to be like really?  really. This scene would have been totally fine if you never spoke.

Then, somewhere in the second season she crosses over and becomes a character.  And eventually, she becomes one of my favorite characters on the show.  So for the past week or so, I've been trying to pinpoint exactly when she becomes a real person.  It could be the episode where she, Kelly, and Steve try and play the stock market, and Steve and Kelly call her stupid for wasting their money but she actually makes a lot of money. And tells them never to call her stupid again.  But I think the real episode is the one where Scott accidently kills himself and David and Donna's relationship begins.  What do you think?

And to conclude this post on Tori Spelling, I would have to say that she has downgraded to pretend status yet again.  Now I love Tori Spelling, and I think her reality show is the greatest, but I follow her on twitter and the abrevs she uses...are like that of a really old person that is trying to be cool by abbreviating but doesn't really get it.  Now I know it might be the nature of the twitter medium, but to me, less is more, not let's see how much we can fit in 120 characters until I can barely understand what you are trying to say.  Example:

bed early ROX...Get 2wtch tv!Modern Family hilar!Ariel Winter is so grwn up!She played"Little Tori"on"SO noTORIous"4 VH1.Miss doin tht shw.


What! It just took me ten minutes to translate that.  Ohhhh Donna.
