As raph and Donnie watch their new sister nikki eats pizza with the other brothers

Raph: why you think she was scared when she heard saying no

Donnie: mostly from trauma apparently someone told her no so many times in a very harsh and verbally abusive way

Raph growls: who would do that to someone sweet as her she didn’t deserve it

As splinter brought tea to nikki and made her laugh in comfort

Donnie smiled: at least we all accepted her included dad splinter they watch dad comfort nikki
