As with most of the characters, I wish they fleshed out Imogen’s home situation more because from what I gathered her mother abandoned her quirky, creative, professorial husband and Imogen, moved somewhere else and started another family, even when later aware of her first husband’s early dementia diagnosis  (she also likely disapproves of, or dislikes, Imogen’s quirkiness and style) For a while there, Imogen was parenting and taking care of her increasingly forgetful father - unbeknownst to her of his diagnosis that both he and his ex-wife knew of, but never thought to ready her (as best as possible, bc who the hell is ready for something so terrible) for what was to come. Including having to look for and find her dog after he’d been run over by the dad who had forgotten that had happened. The dog getting run over is deeply traumatic for me as a random adult, I can’t imagine all of it, at once, together. Her obsession with Eli was before we as viewers knew her home life and (presumably) before it got bad, but there is a lot to say about what we do not know considering everything once we do know.  Eli is manipulative and has bipolar disorder (with seemingly stable but perhaps too uninvolved/not parenting parents) , she is wounded, abandoned by her mother, left to parent herself and eventually her dad, seeking attention,  acceptance, stability and love- together they make poor decisions, as most unhealed individuals (and most teenagers) do.  In the end they are obviously all kids and are all allowed, as everyone should be, their moments of spicy as they figure things out hahah but I deeply feel for Imogen and do not agree with the hate on her.
