Well Sparrow actually kinda likes Falcon. But she's never said anything to him and they're not in a relationship or anything so you can see what happens with Raven, too. It's really down to what Falcon wants. Sparrow is a patient wolf. She'll wait for him through his relationship with Raven if thats what ends up happening.( might be a good relationship at first but will probably fall apart after awhile. Seems like a cool plot though)
