Okay I have a theory. Just hear me out.
So when Magnus tries to get his magic back in 03x14, I think the consequence he might have to face is the fact tha he will start to age faster. Idk maybe all the years he lived try to catch up to him or something. I think we kind of sort of saw Magnus with a bit of gray hair in one of the trailer shots?
Anyways, I think in 03x16, which is called Stay with Me (I can feel the angst now itself yall) is when Magnus has his seizure and gives the death scare we saw in the 3B trailer. They save him (obviously) and stuff happens.
The point is I think either the proposal happens at the end of that episode or in 03x18, which is called Aku Cinta Kamu (get ready to die bitches). This episode is most likely to have the proposal which will he followed by the wedding in the season finale.
I just feel like malec is gonna get married before 3x20 ends - which means that we are gonna get domesitc husbands in the grand finale episode.
I'm not sure if this is gonna happen but a girl can dream...
