It seems to me that each route/character has a different "game" that Sophia is playing (at least for what we saw so far):
- For Sam and Dylan, even if they are on different routes, she is more or less "proactively" teasing them, like in this image (Sam and Dylan), the areola thing (Sam), changing in her bedroom (Sam), the photoshoot (both or Dylan), the dialogue about the dream (Sam). With the difference that she is a bit more proactive with Sam than Dylan, as he is her son, he is more pushy and above all there is the taboo barrier that she has to face everytime before giving in a little bit.
- For Zack it seems she appears to be more relaxed with him, see the tanning salon where she has no problem with him staying and helping with the cream, or at home with the massage and the shower "incident". She does not tease but she think about him almost in a sexual way
- For Ellie there is no teasing, Ellie is in "control" of the game there, pushing and "manipulating" Sophia to break the barriers (taboo + lesbian)
- With Aiden she is just following his extortion scheme while enjoying being exposed to the students (but she's not explicitly/willingly teasing them)
- Patricia is guiding her to overcome her barriers (kiss, nudity etc), if anything she is being teased by Patricia
- With Nathalie she is the voyeuse, at least so far, we'll see more in 6 months with the next next update if that will be the path or there will be a development.
We'll see what happens in this update with the Myers boys, if she will be back to explicit teasing or whatever happens will be set in the "context" of sex-ed. And the elders at the clinic, again there can be some flirting or teasing or something different.
