Adrian felt his stomach drop as Cassie paused in her answer, the effect didn't have time to show on his face as she gave the answer he had been hoping for. Part of him had expected it and the Hologram's voice in his mind muttered something about '90 percent of them say yes'. But he didn't care about that, he just returned Cassie's hug, for the moment he didn't care about the past and right now he didn't notice a lack of old memories...
This was going to be his first adventure - and he was terrified.

"Cassie." He began, not letting any trepidation enter his voice. "If you couldn't fit comfortably inside, based on my observations, you wouldn't be able to get through the door." He grinned down at her, he then stepped back and took her hand as he started to walk towards the TARDIS. He came to a sudden stop and looked back at Cassie's home. "One thing..." He muttered and let go of her hand to and jogged up to the door, he closed it and jogged back to Cassie. "Even if you left the stove on...I'm sure I'll be able to set it to bring you back only five minutes later." Adrian grinned at Cassie again as he took her hand once more.

There wasn't a tremble in his fingers or a look in his eye that gave away how scared Adrian was feeling. Apparently as well as not being able to stay serious, he could hide his feelings very well too.
Adrian stood before the door and rooted through his pockets. "Right rear pocket." The Hologram pointed out and Adrian followed the suggestion. The key fit into the lock with less of a 'click' sound and more of a 'snick' Adrian hadn't noticed that before, but pushed the observation aside as he stood right of the door and tugged Cassie right in front. He looked at her and had his hand on the door ready to push. 
"All of time and space...apparently..." Adrian bit his lip on the last word, then shrugged and pushed the door open before stepping through quickly.

"I don't know how much the heating costs so come in! Don't let the cold in!" Not that it had felt particularly cold outside. The Hologram...or Hallucination, had stood himself directly opposite the doors. Adrian moved himself smoothly around the figure as to avoid contact and placed himself at the console.
Unseen and unheard, the Hologram watched Cassie enter and even raised his eyebrows as she unknowingly passed through him. 

Adrian simply tried to act as if none of what surrounded them was as alien to him as it was to Cassie. He was also doing his utmost to not look at the Hologram. While its voice patterns followed those of the Eleventh too closely to sound like the 'Enemy' the appearance was none the less was too close for his comfort. Adrian also tried to look like he wasn't stumbling around hoping for help from an otherwise invisible guide.
Said invisible guide was playing mute and simply watched. Adrian would have guided Cassie through and named everything...if not to impress her then to find out what they were called himself. Which would have ruined the point of it being him who named each part. 

"How does Victorian England sound?" Adrian asked as his hand came to rest on the date controls. The Hologram finally helpfully whispered a date to him, one that would place them away from any 'dangerous times' as well as a location that would set them near friends of the Doctor. 
"Your friends." The Hologram pointed out. 
Now Adrian looked at the slightly smiling face and looked away again. He couldn't lie to himself, he wasn't sure about the title yet...he didn't feel he had done anything that lived up to this apparently well loved figure.

His silence having passed, the Hologram led Adrian through the controls and the TARDIS finally took off. It did so smoothly and quietly...which didn't feel right, had he been alone, he might have asked the Hologram what was different, but he wasn't and didn't. There was however a case of the 'hand break' not being left on.
Adrian felt the TARDIS land even though the engines were almost silent. Now he let his trepidation show. "As far as I know it should be safe outside..." He looked at the doors and then as Cassie. "But I'll go first to make sure." He added and paused only a moment before he headed for the doors. 

When he opened them he found what struck him as an oddly familiar sight...from the life he had woken to less than a week ago. Staring down the barrel of a Sontaran rifle.
Adrian's eyes followed the rifle up to the Sontaran head and the narrowed inset eyes. Apparently his lack of recognition in the individual sense, or perhaps is lack of calm comment telling him to 'lower the gun' didn't help. 
"Who are you? Where's the Doctor?" The Sontaran demanded.
