[Don't... turn away from him, Souji. Ian grits his teeth, and with a sigh he shakes his head again. In a somewhat shaky motion, he grasps the wisteria to hold it pointedly between them.]
Wisteria is the representation of many things. Among them, it serves of a warning of love that clings too harshly, bringing ruin to the foundation on which the flower grows. The foundation of ourselves - of our memories, our hearts, and the people we've loved--
[Where is he going with this? Ian has to swallow, quickly regrouping his thoughts. He hadn't thought he was this much of a muddled mess after that dream, but clearly some things were still just clicking into place.]
If all you can do is promise that you'll remember this, then I need you to remember that forcing yourself to hold back because of me... It's not what I want. It's not what anyone would want. If something happens, then your memories of me - I want them to be something to give you strength and support you, rather than something that holds you back.
[...and that's how Shiro would feel about him, isn't it?]
