If you had DIK affinity then you will have made more Major Decisions in favour of DIK. At that point, these are all the Major Decisions in the game.
- Fight Troy / Don't fight Troy
- Take Quinn's number / Don't take Quinn's number
- Don't talk to Steve / Talk to Steve
- Fight the Jocks / Don't fight the Jocks
- Party without limits / Don't party without limits
- Accept Jade's advances / Don't accept Jade's advances
- Smoke weed with Quinn / Don't smoke weed with Quinn
If you make at least 5 decisions in favour of DIK, then you will have DIK affinity. Also, the affinity can change right before the M&J scene in ep 4, so if you have Neutral affinity and have made 4 Major Decisions in favour of DIK, choosing to smoke weed with Quinn will change the affinity immediately before that scene.
I had Neutral affinity on my "ride or die" path, and these were the decisions I made:
- Don't fight Troy
- Take Quinn's number
- Talk to Steve
- Don't fight the Jocks
- Party without limits
- Accept Jade's advances
- Smoke weed with Quinn
Just to clarify, you don't "have to" have made one more DIK decision than CHICK to get the acceptance, that's just if a player wants to tow that line between Neutral and DIK, and if one of those DIK decision was to fight the Jocks in ep 2, then they can get DIK affinity in ep 5 by making one or both decision in favour of DIK.
