I think Vi is too fearful when it comes to feelings, maybe because she's used to being left alone like always. That's why she will be too scared to ask Cait. She will have a plan, but the moment she's about to do it Cait will take the lead. I think Cait is afraid too, mostly because she doesn't want to impose anything on Vi, especially the responsibilities coming with her last name, buy she will definitely will be the one proposing.
