So long~
Something that I believe has been abundantly clear for several weeks is that Teddy is no more. He's officially off the cast list and probably not on the friend button anymore as of soon. For anyone wondering, here's some details: He is not dead. He was transported to some alternate (alternate-alternate) reality, though the details of that place have yet to be explored. All traces of him created in this universe were removed with him as well, which I know doesn't directly effect a lot of characters, but anyone that did meet him has completely forgotten this ever happening. As far as this whole universe knows, he was never here. The only hints that do remain are anything that came with him from his own home universe, and that would be Cassie and Billy, and any items they had on their person the day they were transported. Everyone, feel free to think Cassie and Billy totally nuts. Feel free also to use this plot device to shake it up for your own characters. Maybe Teddy did touch their lives in some subtle way so this can send them on a different path if the one they were on wasn't really pleasing you so far. Maybe something of theirs was just in that building that disappeared with Teddy. Maybe you just go on with your lives never knowing this happened.
Anyway, this isn't quite goodbye. Whether I pick him up again sometime down the line when he gets himself rescued from his new reality, or someone else does and reintroduces him to everyone, I'm sure he will be back.
For now, you'll have to deal with more Tony, because he somehow managed to not die yet.
