According to CastleTV, the event kicked off with a fun-filled Q&A panel.
"Seamus and Juliana enjoyed sharing stories from the set and talked about things like the role they’d like to play if they could do any project together," they wrote on their website.
The remainder of the day was filled with Castle trivia contests and VIP photograph and autograph sessions.
And best of all, the event raised over $1,500 for the Animal Adoption Agency. Congrats, CastleTV, on another successful Castle-Con!
