Dr. Jessica Hahn formerly of "Grey's Anatomy"
She may be gone, but she's not 4gotten. The BFF of Dr. Torres who turned into her lover was smart, intimidating, and could talk a blue streak. But she challenged the status quo at Seattle Grace and when she told Torres that she was "glasses" for her(after they slept together)...well, a truer a-ha moment hasn't been had on primetime...
