"Right now... its way too dangerous," he explained. "And its not just this whole mess with Magister. You... you saw what our world is like."
Absentmindedly, R.D. took a bite out of his ice cream and swallowed before continuing. "I have seriously pissed off the wrong people on my world. Ziatoch is after me because I have Lumiya. NightShade has some grudge against me for something I can't even fathom. And... you saw how the fight with Re-Tuul went."
Another bite and swallow. "Re-Tuul's got it out for me bad, and he won't hesitate to use people I care about to get at me. Malvettix already did the same to Alasea to get at me and Matt," he continued. "If they don't think I'm particularly attached to Alasea, she'll be in less risk."
He remained silent for a bit, until he finished off his ice cream cone, and flicked the crumbs off of his hands. "Besides, what business do I have looking towards a future when I can't even reconcile with a past I can't remember? I have to get over that before I look forward to anything."
