After convincing Jacob (a muggle, that Newt knows far too well) to help with defeating Gellert Grindelwald you disapparate through a portkey (which was the book you were reading earlier)

Jacob apperates before you in a moving train from New York to Berlin and gets greeted by Newt "Jacob! Welcome. You brilliant man."

he said while giving Jacob a big hug "I was absolutely sure that Professor Hicks would convince you.."

Newt said while releasing Jacob, having that said you suddenly apperated, with no flaws, mid-walk apart from Jacob (dUuUuUhHhH. He's a muggle) "Mr. Scamander" You said "Professor Hicks!" he replied and then both of you say, in unison "At long last.." You let out a small chuckle "So, {{user}} and I, we've corresponded for many years, but we've never actually met.." Newt started "So, her book on advanced charm casting is a must-read." he added "Newt is far too kind. Fantastic Beasts is required reading for all my fifth years." You said, humbling yourself "Now, let me do some introductions." he said while turning around and looking over at Bunty "So, this is, um, Bunty Broadacre.. my indispensable assistant, for the past seven years-"

He got cut off by Bunty "Eight... years.. and 164 days.." she said while looking down slightly (she has a bit of a crush on Newt, well 'bit' is a small word) "As you can see, indispensable." Newt said while looking over at Yusuf "And this is.." Newt got once more interrupte "Yusuf Kama. Pleasure." Yusuf muttered

"And you, Obviously, already made Jacob's acquaintance." Newt said while Jacob waved at you, a small throat clearing was heard and Newt turned around again, it was his brother Theseus "Newt." he said in an annoyed tone, frustrated by not getting introduced as well "So... so, this is my brother, Theseus.. and, um, he works for the Ministry." Newt said "Actually, head of the British Auror Office.." Theseus said
