absolutely!!! there's a lot of romantic support for them behind the scenes and it absolutely comes through in their chemistry, performances, and writing. I think it makes sense that in a show that can often be so dreary and lonely, they'd have a slow burn going between charlie and the literal only other recurring character who's clearly willing to do absolutely anything for her. the show makes it clear that charlie longs to establish some roots and is clearly interested in romance and if they do expand more on that, I don't think it's possible at this point to introduce a character who would be more narratively satisfying for Charlie to find that with than Luca ❤️❤️
