SAN DIEGO, CA – Panels for "Game of Thrones," "The Defenders" and "The Walking Dead" were the highlights of the second day of the 48th Comic-Con International.

Alas! For the first time ever, HBO's "Game of Thrones" is actively airing its season while Comic-Con is happening. This gave fans the novel opportunity to discuss Season 7 five days after its world premiere. HBO unveiled a 60-second trailer for future episodes — teasing a massive battle to come and the first meeting between Daenerys Targaryen (Emilia Clarke) and Jon Snow (Keith Harrington).

Before cast members Alfie Allen, Jacob Anderson, John Bradley, Gwendoline Christie, Liam Cunningham, Nathalie Emmanuel, Isaac Hempstead Wright, Conleth Hill and Sophie Turner were introduced, their former castmate Kristian Nairn, known for his character Hodor, was introduced to resounding applause as the panel's moderator.
