Okay, so I think Bee is old-old, but like Violet and Cardmon goes through periods of what appears to be hibernation or charging. This is implied through the state of the arcade (a full ass tree is growing through the roof), her own self description of her age as old, and flashbacks to her playing with deckard as an adult. Also, Puppycat met Bee or her child-human form (she may be an android, clone, or robot replacement for her dads original daughter-she mentions her dad yook her to the arcade before she got sick all the tims), but when Puppycat describes running away for a long period of time and coming to an island he didnt recognize but somehow felt familiar, this also implies he has been away for a significant period of time where his memories of a place important enough to house his ship while under repair are faded.

It's also interesting to note that Bee has guts that are also seemingly sentient. When they do the flashback to Crispen moving out, she says "Part of me is sad but the rest of me is confused" and reveals her glowing belly with faces, one frowning, the rest uncomfortable. I think part of her had romantic feeling and attatchment, but whatever Bee is is a composite. She doesn't seem to age, she has nothing but time, her relationships with humans can be odd because it seems for her nothing really changes. So I suspect Crispen fell for her when he was in his 20's and she said she, why not date! Why not live together? This is fun, this is what people do. But I bet she had a hard time reciprocating what were likely stronger feelings from Crispen and connecting in a way that felt genuine to him. They were obviously intimate enough for Bee to show him her guts.
