Observation Without Misery's Links
OWM treats her son as just one of her many projects, giving her a selfish fondness for his existence. As he is most likely one of the last surviving products of her bioengineering facilities' work, she feels as if his life is her only validation in a world where she has destroyed most everything else by her own hand. She is unaware that LHA's existence probably stomps out more living beings than she has.
LHA feels bad for his mother's situation, but knows he is incapable of doing much to help her. He often avoids communications with her to escape a sense of powerlessness, then feels even worse about abandoning her at times she'd need someone to speak to most. Often gives her territory an extremely wide berth.
Often attempts to ignore communications with him due to his inabilities coming off as painful to her systems. However, she often has little choice, as it's either him or utter silence.
Treats her the same as he would most iterators. he responds if he is spoken to, and if not he maintains radio silence.
