Not a lot of context is necessary I think, just this line a person said to their friend: じゃあ、今からいつもの場所に集合ね
I'm not sure if this 集合 implies a group gathering between friends (more than 2) or if it can also just refers to the 2 of them. I usually see 場所集合 used when talking about groups of people so I'm not sure.
thanks
