The 100's Bellamy and Octavia Blake could really use a paternity test.

'The 100' Spoilers: Can Octavia Forgive Clarke? Marie Avgeropoulos Talks Season 3

The Ark's only siblings don't know who their father(s) are, but series creator Jason Rothenberg was kind enough to knock one man off the list of potential baby daddies.

"Don't worry. Kane is not Bellamy's dad," Rothenberg told fans on Tuesday.

As it turns out, the former councilman and Chancellor of Camp Jaha is not Octavia's father either.

"We toyed with this idea, but I decided it made the world feel too small," Rothenberg explained when viewers asked about Marcus' relation to the younger Blake. "I hate when everyone is related."

Does that mean we will never find out who helped Bellamy and Octavia receive those dashing good looks? Rothenberg didn't say but, considering the series high mortality rate, we're guessing the pair's dad is probably long dead. There's a high likelihood that the mystery man never even made it to the Ground.

It's just one of many questions viewers have to ponder over the summer hiatus. Between the shocking City of Light reveal, Clarke's departure, and the tenuous relations with the Grounders, The 100 already has a host of answers to sort out for season 3.
