i'd really like to be able to get into that blacked out room in the spawn lab. maybe there Lust doll could finally figure out why you woke up in a test tube, and in idea for another transformation/power LD could pottentially unlock.... TENTACLES!!!!. all we know so far due to implications is that LD is a either geneticly modified volunteer and possible former scientist, or a lab grown sinthetic life form. imagine this, later after a certain quest, i'm just going to use the flesh thing as example, you go to New Ark Lab, to continue studies on the abandoned lab wich gives way to 2 possible storylines. 1: assuming you regected Succubus queen's love, once you unlock that blacked out floor in the Abandoned lab, you descover sertain samples that spike a flashback, before you know it one of the samples breaks out and enters Lust Doll through either the nose or the mouth, essentially mutating them to grow tentacles from their back wich gives a veriety of abilities and possibilities for sex scenes, if you know what i mean ;) and these tentacles could give possibility to reach sertain high up places or an alternative to crawl over fences. or option 2: assuming lust doll has accepted queen Succubuss' love, their succubus powers keeps this mutation at bay, but eventually after some time streanthens their Succubus powers, but the sample thing develops into a sort of split personalaty simmilar to Yandere Rinny, giving even more possibilities for interactions between yandere Rinny and your own Split persona.
Just brainstorming here... i think i cooked with this one.
