yesyes !! okay basic information,, robinfall is bigender, she/he (with preference for she/her), she's the deputy of kestrelclan! the medicine cat, parrothop (he/they), is her brother :]
robinfall was born shortly after sagestar became leader. he and her brother were/are very timid and cautious but reliable and understanding, earning them their roles in the clan.
as a young warrior, robinfall met a kittypet named sylvia (she/her, name in reference to burn pygmalion by the scary jokes). sylvia is a pretty turkish angora who's fairly popular in cat shows and is often bred with other turkish angoras by her owners. she and robinfall quickly fall in love. sylvia offers to let robinfall move into her house, but her owners aren't happy to have a feral cat walk in, so robinfall has to go back to the clans.
a while later, sylvia finds parrothop looking for herbs near her house and, recognizing he must be related to robinfall, explains that she had robinfall's kit. parrothop takes the kit back to kestrelclan, agreeing that it might not be safe for the kit to stay with her considering her owners' attitude towards robinfall.
while my clans are much more accepting of relationships with cats outside the clans than canon warriors, it was still shocking to many of the other kestrelclan cats when they found out their deputy had a kit with a kittypet. this causes robinfall's relationship with her brother and daughter to be strained, leaving parrothop to do most of the work raising puddlekit (she/they) early in their life.
eventually robinfall does repair her relationship with the two, apologizing for being distant and recognizing it's not fair to project her feelings about her own mistakes on them. while puddlekit is almost an apprentice by this point, robinfall tries his best to be a good mother and prepare them to be an apprentice and later warrior.
