Atlantic Ocean, April 10th, 1912

A Blue Box appears out of thin air on the deck of a ship, unnoticed by anybody. An old man, with long silver hair, emerges. He is wearing a suit with a black cape, alongside a Panama Hat on his head. He wears a blue signet ring on his hand, and uses a walking stick to aid his movement. He is followed by two much younger people, a young man dressed in a suit and a slightly older lady wearing some form of military wear, with a sash. Their older companion doesn't seem too impressed by her clothing choice.

The Trio quietly discuss their lucky escape from the 'Daleks' and 'The Monk', the old man telling his young friends, whose names were Steven and Sara, that he is confident their enemies won't be able to follow them. He then points out excitedly the ship they are on, the 'RMS Titanic'

Sara is unsure why the Doctor is so interested in being on the ship, while Steven is surprised she doesn't know of it, since she's from the his future. The Doctor simply says that what's considered historically important changes, reminding Steven that Sara is from more than 2,000 years in the future. They explain to Sara that the ship will famously crash and sink in 4 days, and decides they should leave soon. As they walk they notice another blue capsule nearly identical to their own. The Doctor is sure it's nothing to worry about, probably just his future self.

They continue wandering for a moment before the Doctor suddenly freezes, staring at another trio of people. Sara looks over at them. There's a young man wearing clothes of a similar antiquity to the Doctor's own, and with long hair. She wonders if the TARDIS they saw was actually the Doctor's past self's, she thinks the man looks like him. He's with a woman who looks quite a bit older, with black hair, Sara wonders if she's his mother. The young man the two of them are with looks like he's barely an adult, and seems almost as lost as Sara was when she joined the TARDIS. Sara then notices her Doctor isn't looking at what she's taking to be his younger self, but the woman.

Suddenly the Doctor shouts at the group. The younger Doctor is panicked, grabbing his friends hands, and runs off. The Doctor orders Steven and Sara to pursue them, chasing the group to the other TARDIS, which leaves. Without giving pause for breath, The Doctor takes them to their own TARDIS, and immediately pursues them.

A woman dressed in black watches the proceedings, then writes it down in a little notebook. The then watches a young man with a shaved head and large ears enter his cabin. She looks to her strange wristwatch, and is about to press a button when her arm is grabbed...
