Orphan Black's Beth Childs isn't going anywhere.

Barley seen since the series premiere, the deceased sestra made a comeback in the season 4 premiere. Sarah (Tatiana Maslany) is looking for answers, and, to help her out, Orphan Black is delivering Beth's tale via a series of flashbacks. "Transgressive Border Crossing" gave viewers a glimpse at the clone's final day and last goodbye.

Luckily, Beth and MK's farewell does not signal the end of the former's tale. More pre-season 1 reveals are in the cards.

"They're a little bit peppered, yes," co-creator Graeme Manson told Entertainment. "Heavier in the front to get the ball rolling, but it's part of the real narrative fun of the season. It's something we haven't really done before, and despite the complexity, for the writer's room, of linking all of these things up, it sure paid off for us this season, I think."

After all, we still have to find out why Beth returned home with blood red hands. MK certainly doesn't know, but, if the skittish clone teams up with her sestras, they might be able to unravel the narrative.

Next time on Orphan Black, Sarah will have to deal with her Neolution implant.

"As Sarah reels from the shocking discovery of Neolution's biotech, she's desperate to find answers. Always impulsive, she follows a lead into a harrowing encounter that requires the help of a reluctant new player," BBC America teased. "Eager to assist, Mrs. S strikes an alliance with an old nemesis. Rachel receives a visit from her keeper and takes a fraught step forward towards recovery. Meanwhile, Helena is mistaken for 'Mrs. Hendrix' when she answers a visit from suspicious visitors."
