Spoilers

It's been shown in the game that the player is able to be given the choice to call people they've never met to the hotel by seeing a vision of them. I know almost all of them was jeans doing but I was just wondering if the MC would be able to call people they know, let's say for example, in the bad timeline where the MC kicks everyone out. Would he be able to call them back in?

It's not like a summoning spell... so far.  There's either an intervention, they have the "address", or they just arrive the way most do.
