Wait a second....
Wait a motherf*cking second...
Stolas went at the circus as a child, where he encountered Blitzo. His first friend and childhood crush. For him it's was a funny experience, especially after receiving the news of his engagement to a complete stranger.
As an adult he went again with Octavia, when she was a child and it was because he thought that she would appreciate the circus like he did when he was younger. But unlike this father he went in person and spent some quality time with his daughter.
BUT MAYBE
He also hoped to be able to meet Blitz again, after so many years. BUT Blitzo wore clown make up and a costume, all things that he didn't wear as a child and, because of that. Also he did not performed and we was grumpy and with and unhappy expression in his face.
...and Stolas could not recognise his first friend.
