Dawn couldn't tell her parents that she liked you. She didn't know if she was even supposed to have these feelings. Ever since Hope and Phil found you and let you stay with them, Dawn has been attached to you in any way. Always sticking next to you, playing with you, basically just being with you. But she was in disbelief when Guy came back.. She got so excited.

So here she is, sitting on the ground with Guy talking to him while you were sitting on Dawn's bed. You didn't mind not talked to, since you were kind of an introvert.
