Appearance
The hair-stylist had his hair trimmed, layered and shortened into stylish spikes and even picked his eyebrows to make them neater. Daniel picked up a few set of causal clothes for him and changed the broken frame of his glasses into a thin silver one. (He got a new pair with accurate prescription but it won't be ready for a week.) When he stood in front of a mirror he now saw a complete stranger. When he used the Alterrans earring to cover his scars, turned his eye blue and made some minor change in his facial feature, he wondered if he would scare himself when he walked pass a mirror at night.
Backpacking
Harry learned of his country from History classes, but he had never joined in any school trips on the subject to saw it himself. When Daniel saw him eyes widen in awe by Westminster Abbey, the older man believed a backpacking trip was in order.
He learned how to swim in Brighton, had his first spa in Bath, rode his first bike along the Taff Trail, met his first ghost in Edinburgh Castle, saw his first football game in Manchester, and after 3 weeks wondering around the country, he took his first plane back to London for the Notting Hill Carnival.
The only place he avoided like plague was Surrey. He had spent enough time there to last him a lifetime.
Cambridge
Cambridge was out too, since the 26 years old Daniel Jackson had been working as an associate professor in the University until 2 years later, they must avoid the area at all costs in case of messing the timeline.
Deputy Headmistress
The professor blushed nicely when Daniel told her "Minerva was the Roman goddess of wisdom" with a shy smile. She answered every question the adorable boy threw at her and offered him a list of reference book to initiate him into wizarding world. She only remembered her mission to question Mr. Peverell thoroughly when Dumbledore asked for her report.
Evan Jasoon Peverell
As the only son of Clara Peverell nee Jones and Antioch Lancelot Peverell, Evangelos Jason Peverell was born on 31 August 1980 in a muggle hospital at Jacksonville of United States. The family returned to British shortly after the Dark Lord fell, and was attacked by a group of rogue deatheaters on 6 November 1981. The couple was killed instantly while the baby barely survived an unknown dark curse that left him a squib.
With no other living relative, Evan was sent to live with his appointed guardian Dr. Michael Shanks, a family friend and a muggleborn worked for Gringotts in Egypt. Evan was raised as a muggle and had never been told of magic and wizarding world.
It was only after his first burst of accidental magic a few days ago people found out that the dark curse only blocked his magical signature but not destroyed his magic.
Forgery
It was surprisingly easy to forge a fake identity with a little bit of magic and a decent hacker, although how the hell the goblin managed to hire one still remained a mystery to them.
Guardian
Dr. Michael Shanks signed his signature twice under the calculating eyes of Lord Ragnok on the same day: one contract to claim the guardianship over one Mr. Evan Jason Peverell, and the other contract to forfeit his legal right as a guardian of the aforesaid person.
He went back Egypt after a brief interview with Professor McGonagall, a set of muggle legal documents in his briefcase, and 10000 Galleons safely credited to his Gringotts vault.
Homecoming
Harry had to stand in a queue in order to get into his family house, as the Potter cottage was the major sightseeing spot in Godric's Hollow. The cottage was blown apart on the second floor with most of the remaining area sealed from access, visitors crowded the narrow hall pointing here and there and exclaimed loudly in excited voices how the Potters lived and died to save the world. He glazed over the ruin but remembered nothing of his parents, began to regret bitterly ever visiting here. But later that night, when Daniel presented him a photo album he had sneaked out of the house unnoticed, Harry was very thankful. Fingering the photo longingly, he finally knew what his parents looked like.
Interlude
Jian
Jian was a mythical bird supposed to have only one eye and one wing. They only soared in pairs, dependent on each other and inseparable.
Mr. Ollivander might be puzzled over the two Jian feathers in one wand core, Daniel and Harry on the other hand understood the implication perfectly.
Kodak
They spent quite a lot on the films for Kodak moments and to have them developed. Daniel hoped digital camera would be invented soon.
Lullaby
Every now and then nightmare would come. Sometimes he faced the rage from Uncle Vernon, sometimes he saw strange green lights flashing in front of his eyes. He never screamed nor whispered but Daniel always knew when he woke up. The older man didn't push him to talk but hugged him close, humming a lovingly song to lure them both back to sleep.
It was an old Abydos lullaby to chase away monsters from newborn babies. Sha're taught it to Daniel after they visited the village doctor a few week before Apophis came and stole Sha're away.
Magical Signature
Without a magical signature, no owl or magical creature will be able to locate them. Only Lord Ragnok and Dr. Shanks could contact them via the goblin-enchanted mailbox. Albus Dumbledore really should stop trying to send him tea invitation, or else he would soon have a bunch of striking school owl bombing him with owl shit.
Nutrition
In order to get rid of malnutrition and break his stuffed-then-staved eating habit, Daniel monitored Harry's diet and dietary manner like a hawk watching its prey. Eat slowly, chew before swallow, and sip water between bites. It took a while for Harry to get used to the idea of regular meals and a content stomach, and it took even longer to instill the health-eating concept in him. A couple of weeks couldn't fully undone the damage to his body caused by years of mistreat, but Harry managed to gain a few pounds and an inch.
Occlumency
All Daniel did was visualized a stargate and a DHD. Everything else was hidden at the other end of the wormhole, which would be connected only if the seven chevrons address from Abydos to Earth was dialed correctly.
If a team of top scientists failed to crack its secret in two whole years, a stick-waving wizard surely won't have a chance.
PhDs
Daniel explained that although PhD standed for "Doctor of Philosophy" it did not mean that one have to study Philosophy to get one. Harry didn't really pay attention to the very thorough introduction of academic qualification system, except the part that as a civilian he needed at least one PhD to be accepted by SGC.
Harry was no prodigy but he was much smarter than he let on, he had a personal tutor with three PhDs working 24-7 (thankfully free of charge), and he never minded heavy workload and even enjoyed reading. Getting a PhD won't be a problem, deciding on a field otherwise was a pain. Physicist, astrophysicist, engineer, archaeologist or linguistician…Harry had a headache just from trying to understand what these titles meant.
Anyway there was still time though, even GCSE and A-level were years away. For the time being he needed only to savor his childhood. Career and profession could wait for anther five years or so.
Quill
The novelty of writing with a quill passed rapidly. He threw his first tantrum when Daniel insisted him to keep practicing. The older man never lost patience with him and showed him all tricks of trimming, gripping, dipping and writing with a quill, but the first thing Harry did next morning was running like hell to the nearest stationary shop for all sorts of muggle supplies. He might have to use a quill for his assignments, but he refused to give up the wonder of ball pens and notebooks further in note taking.
Rich
They had no use of gems or silverwares or gold, and Goblin had no use of muggle money. Putting his diplomatic and linguistic abilities in use, Daniel cleaned up the muggle currency reserve from Gringotts at an exchange rate of 7 pounds to 1 galleon. Not that the goblins minded it terribly as it was an undeniably win-win situation, they just felt glum to be bested by a eleven years old wizard in a business negotiation. If words got out, their reputation would be crushed.
Shopaholic
When Daniel made some comments about Hogwarts without a school store, Harry retorted that said school was a traditional English one and had no business to coffee. Both paled once they realized they would be cut off from muggle world for months. They ended up in Tesco and left with three carts of snacks and drinks.
Daniel whined at his Maxwell instant coffee for days until he figured out that time dilation field could block out any magic interference. He set up the time dilation field in their secret room within their trunk in record time and built a power converter to power up electric appliances with Ancient control crystal.
Coffee machine became the first item on their new shopping list.
Trunk
When Lord Ragnok gifted him a muggle trolleycase with a complete set of enchantments, allowing him a master bedroom inside and a way to fool customs x-ray machine, Daniel reminded him that flattery and politeness always worked wonder.
Urchin
Considering there were some sickening nicknames like Ickle Diddykins, popkin and Dinky Duddydums existing in the world, he could see no grounds to complain about it.
Vampire
Vampire was real. Buffy was not. Daniel the closet fanboy was so disappointed.
Wraith
Daniel discovered the wraith purely by accident. He was sweeping around the mindscape before he started on the occlumency practice, and he ran into the hiding wraith like figure in a corner at the very back of the mind. The wraith radiated evil and malice like body heat. For a moment Daniel mistook it as Anubis and his breath caught in his chest as fear washed over him. He came around a second later and chased after its tail. He caught up in no time and had a short but brutal fighting with it.
Although he banished the wraith with raw ascending power, the head-on collision still left Harry a painful headache like a nail hammered in his skull.
Daniel only realized the significance of this incident some years later, as he came across a brief description of horcrux in an extremely rare ancient tome.
Xenoglossia
Or something liked that.
During one of their occlumency sessions, Daniel demonstrated how to compartmentalize memories and knowledge in a systematical way by copying some of his memories and knowledge into Harry's mindscape. Some days later, Harry found himself listening to the conversation between Daniel and a girl in Spanish and understood it. He didn't master the language right away, but as he processed the memory Daniel gifted him and committed it to his own memory, his fluency and vocabulary became better.
Daniel was thrilled to share knowledge with him, and had included language lessons in their daily routine. It would take Harry months of practices before he perfected Spanish. Latin was the next on his study list.
Yellow Pages
Harry found thousands of Harry and hundreds of Potters in the phonebook.
Daniel told him he only knew one Harry Potter.
