This was a filler episode but what a virus she planted in the hospital computer system and fact that it was triggered by her death was sad it's a good thing her boyfriend knew about the virus otherwise the hospital would be screwed
.
Now the only problem i had storyline was how the hell she knew chemical formula for the drug unless she has medical knowledge no way she should be able to know chemical formula symbols for that drug it wasn't common drug it was specific drug.
. I guess they got tie up the episode by the end.
