Interesting choice. I've never watched One Tree Hill, so I have no idea what she's like as an actress but she does seem very young for the part. Whatever happens I really hope she has some charisma. The show could really use some now that Munch rarely gets to speak, Benson is spending her days longing for a baby and Stabler is gradually self destructing under his massive ego.
I do hope we'll see Stephanie March reprise her Alex Cabot character, even if she won't be SVU's ADA.
