part the 2.
Jack decided to start with the train - better to start with the part he knew best, really. "It hops all across realities and times and picks people up as it goes - all from different times inside their own reality. Take the guy I know. He comes from farther into the future than I do. So did Rose." Oh, Rose. She had left again, but Jack wasn't nearly as despondent about it as the Doctor. The Doctor had grown ... odd in the future. Mopey. Jack didn't like mopey Doctor. Jack wanted adventure fun Doctor back. Never mind that, back to the train. "There's no way to get off it, unless it sends you back home. Sometimes the train will stop in other realities, but there's no way to stay off the train there either. As for Lily, I don't know when she comes from, but it's before she dies. Train took her roommate away a few weeks ago too - back when it took a bunch of the wizards off. Or maybe that was the last round. There's so many of you, it's hard to tell."
Remus was thoroughly confused. Just when he thought he might have a grasp on the situation Captain Jack would tell him something else confusing. His heart skipped a beat. "Dies? When does Lily Evans die?" His head was now spinning so badly that he had to use his hand on the wall to steady himself. "Captain Jack, what is going on?" He thought he might faint. Lily Evans wasn't allowed to die unless she was a very old lady with a large family and lots of grandchildren and greatgrandchildren. If Lily was that old on the train what did that mean for him? How could they come from two different times and places at the same time.
He was taking deep breaths to steady himself and was only comforted by the idea that James had been here as well. "When did James leave?"
"Whoa, whoa," Jack said gently, placing a steady hand on the boys shoulder. "I don't know that much. Lots of people on the train are dead in their realities. I just know she's one of them. As for James ... Potter, right? He was here, Harry was here. You were here, Snape was here, Jamie I already got, and there's a few others I can't remember, but pretty sure if there's a redhead on the train they're a Weasley or a Potter." He didn't know much about them, just who they were. They were everywhere. Then they disappeared. Then they came back. Then they disappeared. Rinse. Repeat. "It's the train," he said softly. "We don't know why it does what it does."
Remus's heart jolted at the mention of Snape. Jack didn't seem phased by it. A Death Eater. On the train. Lily Evans died at some point. He didn't shrug Captain Jack's hand off. He needed the comfort right now. This was a lot to process. "Snape." He said it softly. Snape had been here. "Are there other non Weasleys and Potters? Besides Evans?"
"Snape was Lily's roommate," Jack said. The food in the kitchen hadn't been up to par for a few days after that. "Otherwise ... I think there was a Tanks? Tonks? Something like that. There's a Granger wizard too, and ... I think one more non-Weasley/Potter, but I can't think of his name at all." Jack rubbed the man's shoulder, "Now, you okay? It's a lot to process. Sometimes the train plays tricks on us."
Remus was still a bit short of breath. He turned around and saw his name on the door. "Oh." So it was real. Tonks was a name he recognized, but only because of Sirius's cousin. Granger he didn't recognize. It made sense that he wouldn't know them all. The Wizarding world might be small but that didn't mean Remus knew every name. His hand still gripped his wand. He didn't think Captain Jack was a danger but he didn't trust the situation to let go of it yet.
"I'm fine." It was the easiest response. In turn he would be. He would like to walk the train and see who else he might recognize. He needed to also process the idea the Lily Evans died or would die. James had been here so he could come back. There was the matter of him also having been here which he distinctly didn't remember himself doing. Future him. "How long have you been here, if you don't mind answering?" Remus asked, still polite as always while trying to clear his head. A general timeframe to work with would be good. Remus was the sort who could readily accept a reality of a situation. This was no different.
