Shannon Woodward and Jeffrey Wright as Elsie and Bernard Lowe in a still from Westworld.HBO

Sunday's episode of HBO's new science fiction Westworld will see Teddy, the character essayed by James Marsden, getting a new storyline, and it looks like the Man in Black isn't Teddy's immediate threat.

The first two episodes of the drama saw Teddy, who is one of the new arrivals of Westworld, going through a similar routine of trying to meet up with his sweetheart Dolores. But things take a turn for the worst when they arrive back at her farm to see her family murdered. Sadly, Teddy, too, gets killed by the Man in Black, and the next day he repeats the same story.

Who could be the new villain in Teddy's life? Is it a host or a customer? Episode 3 will probably reveal the answer to these questions. According to the synopsis for the next episode, fans will see Elsie and Stubbs heading into the hills to find a missing host and Bernard will start investigating the origins of madness and hallucinations within the hosts.

Meanwhile, fans of the show have come up with some interesting theories on who could be behind the glitch that allows the hosts to recollect their past, and all speculation points towards Bernard. As per one Reddit user, Bernie is secretly working to take down Westworld because his son was killed in the critical failure three decades ago.

Another Reddit user feels that the second episode may have shown us the first meeting between Bernie and Dolores. Here's what Reddit user brettter21 has to say:

I've also been chewing on the possibility that the little boy is actually the 30yrs-younger Bernard Lowe... Although we know from the dialogue that the little boy's name is "Jacob", there isn't any mention of Bernard's middle name... e.g. Bernard Jacob Lowe or Jacob Bernard Lowe
This also coincides with the little boy's fascination with Delores even after walking through SweetWater from the train. The boy is fascinated with her from the moment he meets her and we know that Bernard himself has an affinity for Deloris from Episode 2 when he talks about there being "Something Special" about the way she thinks.
Did we unwittingly see the first meeting of Delores and Bernard?
