Royal Wedding was actually slotted in after the previous story went online because the feedback suggested that people DID actually want to see Penne’s wedding. Now, I didn’t want to go into the full Gallifreyan ceremony, as I had already written the Alliance of Unity of The Doctor and Rose in great detail and didn’t want to pre-empt it with this story. So the main part of the ceremony is glossed over, but Penne and Cirena are married and the story turns to Epsilon getting drunk and celebrating that he has killed his cousin when The Rani contacts him and tells him he has done nothing of the sort. At which point Epsilon realises that Penne and Chrístõ are doubles – he had not seen this before – and recognises the House of Ixion’s crest on that of Adano-Ambrado. He begins to put two and two together and make five.

How Epsilon knew the House of Ixion’s crest at a glance may or may not be explained by future events.
