OK a couple of things here:
1) Passive Dylan: Invites Sophia to the basketball match and watches her interacting with his buddy...
2) Active Dylan: Cancels the basketball match and asks Sophia on a date night.
3) Dylan hooked with Emma: He tells Sophia that after the match he is going on a date with Emma.
4) Or he tells her about Christine's party
5) In GW route if Mr Harris saw Sophia in the surprise dress then something could happen between the three of them (Liam+Sophia+Mr Harris)
6) Or in the GW route again they go on that restaurant and have some husband&wife moments...
Not a bad evening in the end
