Why isn't Izzy cashing the check?

Always with a flair for the dramatic, Izzy had an epiphany after talking to Burke (she has TWO good hands) as well as after seeing Christina doing a 'Running Whip Stitch.' She decided she needed to take advantage of her ability to help people and declared (as she stuck wrinkled and spilled-on 8.7 million dollar check to the refrigerator door) that this money would be used only when she had found a way for it to benefit people other than herself.

Izzie's happy too. She shows Meredith and George the $8.7 million check -- and promptly spills orange juice all over it! She talks about what she might do with the money -- maybe open a bed and breakfast. They anxiously urge her to deposit it in a bank, and she says she will, right after she cleans out her hospital locker. She later tells Addison she feels guilty about the money.

Burke is called into surgery and he and Cristina work out a code if his hand starts to get tired. During the surgery, he coughs and she asks if she can practice her running web stitch. The other interns are insanely jealous. Izzie goes to the Chief and says that she has all this money, but all she wants is to do a running web stitch.

Izzy isn't cashing the check because she doesn't want her relationship with Denny to have a price tag. Maybe she will never cash it.

She wants to do something positive with it. She's not sure what that is right now, and said that she won't cash it until she knows. God, I'm so happy she went back to surgery! I'm waaaay too invested in this show. LOL

She isn't cashing it because she is going to return to seattle grace and use that check to open a cardiac care wing named after Denny.

She is trying to make up her mind what she wants to do with the money she wants to make denny proud of what she does with it so it is taking her some time to decide.

I think she is looking for something constructive to do with the money. Maybe she will do something to help Burke. Who knows.

Because she's stupid and doesn't want to cash or deposit it until she knows what she will do with it. Why she doesn't want to earn insane amounts of interest on it, i have no idea, but whatever.

I didn't know she positively went back to surgery. I think she is confused about what to do although it is not baking!! She will find a cause and donate it all I think, what do you think?

she say she wants some good to come out of the check, until she see what that good will be she won't deposit it to the bank
