5./4. Thomas and Abel Teller
FXAbel and Thomas haven't made an impact as characters as much as they've been the catalyst for a number of events on the show. Abel's kidnapping was the primary focus of the series' third season and their long-term well-being has been a genuine concern for Tara and Wendy's storylines. Now that the former has lost her life for simply trying to save her children from a terrible future after all of Jax's false promises about leaving Charming together, their fates are completely up in the air. Will they end up with Wendy? Will Jax survive the series to raise them how Tara wanted, free from Charming? Will the cycle continue and the boys be destined to be a part of the club? Will one or both of them end up as casualties of the final season? Whatever happens, the boys' fates are an intrinsic piece of the show and especially of the final season. With Tara out of the picture, it feels like the possibility of a happy ending for them has dwindled drastically, but viewers are certainly looking forward to seeing what Kurt Sutter has in store for the innocent siblings.
