WARNING: Major spoilers ahead for the latest episode of Game of Thrones! Read at your own risk...
Game of Thrones made the wishes of many fans come true last night as Gendry, the long lost bastard son of Robert Baratheon, finally returned. As some would say, "His row is ended."
Gendry came back to Flea Bottom to continue his work as a blacksmith, and to be ready to exact revenge on the Lannisters for what they did to his father. The young man reveals to Ser Davos that he fights with a mighty warhammer, similar to the one used by King Robert.
Since the hammer was only on the screen for a short time, many didn't get a chance to see all of the small details within it. Luckily, HBO released a slew of still images from last night's episode (which you can find above), and one of them focused on Gendry's incredible weapon.
If you look closely at Gendry's hammer, you'll notice that he has worked in a very intricate design at the head. The horns of a stag wrap around the top part of the handle, signifying that Gendry is fighting as a Baratheon.
A bastard fighting for his father's house isn't that uncommon. After all, Jon Snow — who isn't exactly a bastard after all — was treated as a Stark for years. The difference here is that Gendry didn't spend a ton of time with his father, as Jon did with Ned.
Gendry mentioned to Davos that he wanted to make the Lannisters pay for what they did to his father, so it's clear that he does hold some loyalty to the Baratheon name. However, putting the symbol of the house on his weapon takes things to another level. The Baratheons have basically been wiped out entirely — providing Stannis is actually dead. So Gendry's imprint signifies a possible resurgence of his father's house, and the notion that the Baratheons have unfinished business with the Lannisters.
What's even more intriguing is Gendry's newly-formed friendship with Jon Snow. As King in the North, Jon would likely have the ability to legitimize Gendry as a Baratheon, just as Cersei did for Ramsay Bolton a while back. If this were to happen, House Baratheon could be re-established under Gendry, and they could once again fight alongside the Starks to take down an evil ruler.
Robert would certainly be proud. Well, unless he was too drunk to notice.
