ROFL worst father figure ever but Gaia probably still brings him lasagnes randomly :D. She's just so zen about everything, she probably doesn't even care that much that he can be cruel, blah blah nature can be cruel, so she can't exactly blame him -- that said she still might shake her head from afar all disapproving-like on occasion, those poor little defences humans. Gosh, Dad.
Gaia will be sweet to Hades, I think. In a way she probably sees him/his realm as the other side of the coin and Tartarus is her brother who is down there anyway so. Also Demeter is her granddaughter, what up tenuous family link through that idk. I think she's probably quite pleased that Hades and Persephone are still together, that just warms her earthy heart~ WELL DONE, HAVE A COOKIE 8]
Aww Peter, why so adorable. Gaia will absolutely bother him with questions about her dog if he's ever sick or anything like that -- though he's usually in obscenely good health thanks to living with, you know, Mother Earth. She might just talk to him about animals anyway, AREN'T THEY WONDERFUL~~
