When discussing a situation where something or someone is starting to become relevant or noticeable, there are numerous ways to express the idea of "coming into the picture." One could say that they are "emerging," "entering the scene," "arriving," "showing up," "becoming apparent," or simply "making an appearance." Other similar phrases might include "becoming visible," "coming to light," "joining the fray," "coming onto the radar," "making an impact," or "being thrown into the mix." Whatever phrasing one might choose, the idea is the same: something or someone that was once absent or obscure is now becoming a significant part of the situation at hand.
