They are minutiae, in my version I choose, for me they are married, or almost.MC and Alexis are not dating at the minute just hooking up
On Layla and Alexis I solve simple, two different games, in one I go to Alexis and Erynn and in the other to Layla and I ignore Alexis.I'm still waiting for the blowout of Lexi and Layla being sisters.
Nikki remains, to understand if he will have an important role or not.
