I'd never heard of her before, but now I know what she has been in (like, House)

^yeah, same

I knew her from House.. Loved her there!!!

From House MD & How I Met Your Mother :)

^ mostly from himym though

And she was in Star Trek for like two minutes. XD

I saw her on House and How I Met Your Mother.

The only actors I knew before I saw them from Once Upon A Time are Ginnifer Goodwin (Ramona and Beezus), Jamie Chung (Grown Ups), Joanna Garcia (Reba), and Bailee Madison (several things but mainly Bridge To Terabithia).

From House :3

I had seen her in Star Trek and a couple episodes of House (which I watched half a dozen times) but didn't really start following her until Once

I've known JMo from OUAT and I've realized that I've seen some works with her in them like House (I've never actually watched house, I've seen only few episodes when there was nothing interesting on TV :P) How I Met Your Mother, Mr. and Mrs. Smith (I know she had a very small role here) and I've also seen a movie of hers with Ben Affleck I don't remember it's name

How I Met Your Mother

Yeah from House

From House.
