Merlin: A sad recluse, 100 years of age and still waiting for his other half to return.
The Doctor: A strange man with stranger clothes, likes to talk. Has also lost a loved one, unfortunately she can’t return (or can she?)
Merlin learns of a new threat to Albion... Aliens.
Basically the Doctor shows up in Medieval Britain and helps Merlin out of a rough spot (100 year depression). When he leaves, Merlin has another purpose. He’s not going to sit around moping as he waits for Arthur, he’s gonna live a little and protect his home.
- Part 1 of Aliens of Albion
Elena and Mithian move in together and Elena bumps into her ‘ex’ Arthur and realises how much they’ve both changed. And of course, visiting Ikea together means you are officially official.
