I believe that Roger will leave Shakky alone, as she is not interested in him. I believe that Roger knows that Shakky is only in love with Rayleigh, and this might make him realize what a hypocrite he was towards Gloriosa. I believe that Gloriosa should play hard to get with Roger with his love for adventure. She could provide him with locations to the road poneglyphs from her adventures with the Rocks pirates.
