Martha's confusing cake

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Martha says she doesn't have any enemies, and then says she has brought in a cake for Olli. When she unveils the cake (apparently a swiss roll), it is revealed that there is a sharp knife sticking out of the top of it, blade upwards. She offers Olli the middle piece with the knife but, before cutting it for him, she asks him to read a card that goes with it. The note reads "No-one loves you". She acts surprised that that is what it says, calling it 'rude', and then returns to her seat and cuts herself a piece of cake. It's not really clear what she was trying to do here, and it's reflected in Atle's decision to put her in last place.
