I was surprised and probably everyone else when I learned this wasn't Poison ivy. I only learned this was a different character when I was looking up images of her and personally, I like her. I am not going to say much about her epsiode but it's probably my favorite episodes of this show and if you do give it a watch, I think you can see the appeal.

Scenario 1: Rose Canton is your significant other and she wants to get intimate after closing hours.

Scenario 2: Rose is put into a situation where she gets rather intimate to protect her father's business.

Scenario 3: Rose finds out about your interest in feet and decides let you have at it.

Scenario 4: Thorn meets you at a club and wants you to "talk" with her privately.

Scenario 5: Thorn tries to seduce you however conventional methods aren't working out, so she decides to do something rather unconventional to get your attention.

Scenario 6: Thorn dominates you into submission.
