Katniss made her Mum swear to look after Prim and not 'fade away' as she did when her Dad died. She told Prim how much she loved her etc. Prim made Katniss promise that she would try to win. The baker (Peeta's Dad) visited her, he brought a bag of cookies and he said he'd watch over Prim, make sure she wasn't hungry. Madge (the mayors daughter) also visited asking her to wear her mockingjay pin as the district token (this is how it is in the book- the film is wrong). Gale visits as they're best friends and I think that's all!
