'Game of Thrones' Season 6 updates, rumors: Upcoming chapter to reveal deeper connection between Tyrion and Daenerys?

HBO's hit fantasy series "Game of Thrones" is nearing its sixth season premiere which will fall on Sunday, April 24. To further excite the fans all over the world, a new promo teaser for Season 6 was released which revealed some interesting bits, as well as previews to the characters' ongoing plight. There is also one particular scene in the promo which would suggest a confirmation of a long-time rumor among the fans of "Game of Thrones" and its source material, "A Song of Fire and Ice" book series.
The Bitbag mentioned a huge speculation about a deeper connection between two of the key characters in the popular TV series: Tyrion Lannister (played by Peter Dinklage) and Daenerys Targaryen (played by Emilia Clarke). It was only in Season 5 when the characters hailing from two different dynasties finally met, though it was noted that Daenerys and Tyrion have not yet met each other personally in the books' version. This season, the angle that Tyrion is actually a Targaryen himself and a brother to Daenerys might be explored.
The introduction of the promo has Tyrion's voiceover while several scenes of the main characters are flashed. He goes on saying a deep but chilling line. "Whoever you are, wherever you go, someone wants to murder you... Are you afraid?"
Towards the end of the teaser, Tyrion was shown holding a torch as he ventures the dark chamber of Daenery's remaining dragons. It seems like Tyrion is becoming fond of the dragons, which was not made apparent when he crossed paths with the Mother of Dragons and her children in Season 5. One of the dragons was shown to welcome Tyrion with a fiery breath, although it was not seen if Tyrion survived the overly heated encounter. This scene was found by some fans as an indication that Tyrion himself is very much related to Daenery's dragon heritage.
It is rumored that Tyrion may actually be a bastard son of The Mad King, Aerys II, who was the dethroned father of Daenerys. It was known that The Mad King was deeply attracted to the wife of Tywin Lannister, Joana. It is possible that during his reign, he may have forced her to be in a relationship with him which could have resulted to Joanna being pregnant with Tyrion. This betrayal could be one of the reasons of Tywin to help the late King Robert Baratheon to stage a coup and bring down the Targaryens, as mentioned in What Culture.
This speculations about Tyrion's Targeryen heritage will either be confirmed or dismissed when Season 6 airs. Also shown in the promo are Jon Snow (played by Kit Harington) who remains lifeless with an unseen person placing his or her hand over the Night's Commander's head. Bran (played by Isaac Hempstead Wright) was shown startled by the Night's king, Sansa (played by Sophie Turner) was seen hiding, and one of Daenery's dragon flying above a huge Dothraki platoon.
