Well, been a long time since I had net! Let's see how much has changed! First off...
Dalton
Why are people such Dalton-haters? Just because he can't beat your whole party that means he is weak and pathetic? He has control of the Golem family, has great military skills (Via becoming leader after the fall of Zeal, as well as the Porre army.), and great technological knowledge. You didn't see Lucca adding the wings to the Epoch. He also reached somewhat of a rank in Zeal, which is a lot in itself, since there were so many natural magic users to compete with in Zeal. He is obviously a person of great power. Now, if they make an FMV ending, it is obviously of importance. If Dalton was indeed the one who took the Masamune, this would hold specially true, since his dark dreams were stronger than the dreams of Melchior, Crono, Cyrus, Frog, and any of the other Masamune users in history. Now, I just believe that the music that played the last time you meet Dalton is to reflect what the party thinks of him. They underestimated him, and paid the price.
Magus
I don't fully understand all the detailed theories and all, but I do think he's the Magus who was on the team. Maybe he's not using "future" in a literal sense. He just means that Lavos was already defeated. I know this will sound silly but...Didn't Marle say that the the Time's Eclipse was cold? That would explain why Magus was using his cloak. >_>'
Don't any of you believe that saving Schala was his intention from the beginning? He knew he would not be able to be at peace with Schala as long as Lavos was still around. To me, destroying that threat was more important. Once that was taken care of, his mind would clear, and he'd have time to find Schala and cherish his time with her.
As for Magus being emo...He was always balancing out his negative emotions, anger and sadness. Anyone that has gone through what he has, would be mentally crushed. I mean, look at how Schala wanted the end of existence. I'm sure that underneath his rugged and sadistic exterior, he was the saddest of all beings. He had always thought that the only thing that could beat might, was even greater might. Spent years and years growing stronger. It became even more of a philosophy. He failed tragically, and once he found out that he could not do anything, no matter how strong he grew, he'd fail. This would obviously crush everything he believed in. His current existence would be useless, and a burden, and he truly didn't know of any other way to save Schala. I think he wanted to start anew, with the hopes that by some unlikely miracle, he'd find another way to save her. If he is Guile, he chose a different path (Enigma?) than brute power. Or MAYBE he is working for Belthasar the whole time, and cloaking himself as he follows the CC team around, like the 4th shadow might hint. I myself always thought that Magus never found Schala, so he went mad(dder) with hatred, and stole the Masamune to wage war on Guardia 1,000 A.D. Then the Masamune would absorb his evil nature, itself being tainted, while Magus was cleansed of both his evil nature, and memories. He'd then put on a mask, call himself Guile, and make up an age for himself. Oh well, I was at least partly right. >_>
By the way, if you choose to fight Magus, are you sure he dies? I always thought he just escaped, and returned Frog back to human form later out of respect. I don't think he held enough hatred towards Frog to fight him to the death. He had more important fish to fry, and decided to escape. That would explain why Magus appears wether you fought him or not.
One last curiosity, and the silliest of all...Were the Shades, and Dalton using elements in place of magic, or am I drunk? o_O
