Mika just ignored his comment about her being a princess, instead just scoffing at his words as her only reply. She didn't take offence to his words, as she was so used to him calling her a princess. It was never a case of her not liking junk food, of course she did but she also believed in a balanced diet and she didn't want either of the two men in her life just living off of junk and nothing else. She didn't see the harm in looking after them both. SHe did still buy some of the things Bobby requested, it's not like she changed absolutely everything. 

She smirked when he nudged her back a little harder than she nudged him, but took it nonetheless. She actually found it quite sweet that he was a bit of a suck up to Bobby, and enjoyed calling himself 'the good kid' out of the two of them as it meant there was always a playful atmosphere between the three of them and if that she was the rebellious one then quite frankly? So be it. After he called out to Bobby, she heard her uncle call back from the hallway as he came back downstairs, "Alright! Thanks boy!" before Bobby muttered under his breath 'ten points to Dean' so neither of the 'kids' could actually hear him. It was entirely petty but he had to admit there was some kind of enjoyment out of pitting the two of them against each other in the sense of giving them points for whenever they did something he wanted. 

Seeing Dean find the pie and whiskey and clasped booth like they were items of the holy variety she had to chuckle before he spotted the dye and looked utterly confused. She noticed how he put the whiskey down on the counter but not the pie and had to smirk softly to herself over it before letting her face become a bit more serious and look at him in the eyes. "I think it's time I said goodbye to Kenzi and become me again....but a new me" she told him honestly.
