One day, Parmala is finally abandoned by Piriram, because of how abused and worthless she really was. She had been full of abuse scars by the time she reached 19, thus she's technically an adult, albeit a rather short one at 4.11 ft. Nanga however, is at least of average height at 1.65 metres due to being raised primarily by the good Yetis.
Thus, she is also nonverbal as usual, always showing similar or even bigger signs of developmental delays than that of Nanga, who is only recently starting to speak in his own words, because of his autism being used to many things about nature.
'Nae? Have I never met a grrl before?', Nanga said.
