Dominic Cobb, Temperance "Bones" Brennan, Remus Lupin, and Buffy Summers would really be loved over at the panfandom comm f_rogers. I also have a character needing a storyline that, really, could be filled by any number of characters.
Inception - Dominic Cobb - Ariadne ([Bad username: redscarves), Eames (<lj user=]) and Arthur (merry_chase) would love to have Dom Cobb about. Okay, Ariadne might like it more than the latter two since they may or may not still be sore over some aspects of the Fischer job, but the odd little family needs to be reassembled. Ariadne also needs someone around that she can ask for dream and life direction related help from as she's (still) ever curious and now troubled with the idea of just being an architect in her waking hours. I have a couple of line and potential plot ideas that Dom could be involved in that I would happily discuss with anyone interested.
Bones - Temperance "Bones" Brennan - Lance Sweets (sweet_lancelot) and Angela Montenegro (paint_by_bones would love to have Brennan about! How would the react to being taken to an alternate universe wherein otherwise fictional characters are real and living together in a large castle? This has epic written all over it.
Harry Potter - Remus Lupin - James Potter (cervine_) and Sirius Black (pad_foot) could both use having their friend around, and really fellow Order member Benjy Fenwick (benjywenjy) could use having someone about to try to keep his assigned roommate Sirius in line. Regardless if MWPP or Trio era, he would have plenty of people eager and willing to interact with him in positive or conflicting ways; he could have a lot of potential.
Buffy - Buffy Summers - Dawn Summers (niblet) has an adorable, newborn daughter. She could use having her big sister around during this time. At the same time, there are a lot of Supernatural (Castiel, Dean, Jo, Sam) characters around that she very may well get along with. Buffy would also have a chance to live a somewhat normal life with no guilt... aside from the absolutely bizarre things that happen randomly to the inhabitants, of course.
Storyline - Any Fandom - I would love to have a friend line for t_davis. She can have somewhat of a cold exterior, as she's guarded, but can be quite loyal and amusing when she thinks someone is worth her while. I'd be happy to discuss personality types and options with anyone who might be interested.
