Yomi chuckled a bit as they neared the Shogun's chamber. "When did you start saying all the right things?" He asked teasing her as usually she was the rough, insensitive type when it came to semi-emotional crap like this. "Well I guess it doesn't matter. Let just see how this plays out." He then said quickly changing the subject. 

"Glad to see you back Yomi." Hiro, the shogun, said calmly as rose from his seat. Kasumi remained seated a calm smile on her face. "It's good to see you. Both of you." She said with a slight giggle as she looked over the two. "Um... Yeah... So... How are we going to know whether or not I'm really your son?" Yomi asked cutting to the chase. "Right... Well..." Hiro began calmly before glancing back at Kasumi who nodded.

(I have no idea what to do >_> 
If this were modern we could do a blood test or something XD)
