So that would go hand in hand with Misty saying she met RC and started talking to him and they began dating and a month later they were living together. Hmm...that's quick for a 17 yr old doncha think?
ETA: MC wasn't 17 until after she started living with RC. She was 16 when she moved in.
Just because she may have met Amber in April does not mean that she had to have met Ron at that time too. Maybe she met him much later on, like Oct. And no I dont think its out of the realm of possibility that she met Ron and moved in a month later or even sooner.
