I wonder what Gob genuinely likes. As in something that interests her that isn't taken from someone she's infatuated with? This year she's spent most of it (before lock-down so no excuse) in pyjamas, perhaps that's her style, that and watching mindless TV all day every day which is something she knows people aren't interested in so she has to morph into someone else.
She isn't interested in learning or educating herself unless is means immediate profit ('design' and 'drawing' now right? If that doesn't make her £££ she'll stop it straight away), what style fashion wise does she actually like? What hair colour does she prefer? It's as if she's blank and empty and takes on the personality of people she sees as popular and it's a little terrifying (and very sad).
Perhaps she is a little like her beloved Monica Gellar after all, when she was described as the empty vase in that poem.
