She goes there only if she completed the 4th task.
Then there are 2 previous events that *could* influence what is gonna happen in this event with Aiden:
- whether she intervene or not in the bonus scene
day20_Sophia_prevented_Andre_Aiden_having_sex_with_Jen
(intervene) or
day20_Sophia_saw_Aiden_Andre_with_Jen_having_sex
(stay out of this)
- not clear why he chose to use 2 different variables when the two are mutually exclusive but I diverge...
- whether she asks help to Morello or not (and based on the previous choice that could include Jennifer, who is not there)
day20_Sophia_asked_Don_Morello_for_help
André will be still pissed for the slap, Aiden for the possible intervention during the bonus event.
The first one *could* probably set the tone of some dialogues, the second one will probably determine the outcome of the event especially if Morello's boys show up. And for example the choice it is mentioned to proceed with the meeting or not might be conditioned to the fact that she has an ace up her sleeve with Morello. Pure speculation but it's just to give an example of how they can influence this event.
Now it seems that this could be the 5th task, something could happen if she decides to meet them.
Or, as usual, Aiden may ask something to have fun with the others and then give her a task for the next time either in school or elsewhere. At the moment everything is open.
It's listed as "meeting Aiden", so it could go either way, he didn't listed it as "5th task" to avoid spoilers or it's just the meeting with some "side action".
