Thought Theseus might like to have a little fun with Newtina in the suitcase. :)
I have no clue what time this is all happening or the circumstances surrounding it- just wanted to show some friendly sibling love! (note: may contain very slight CoG spoilers.)
. . .
Tina shook her head once Newt had walked out of earshot. "Newt hates your hugs, you know."
Theseus smiled, still watching Newt, who was speaking softly to his bowtruckle. "I know."
"Then why do you-"
"He's my brother," said Theseus simply, as if this was all the answer required. A few seconds passed before he continued, his eyebrows going up a bit mischievously. "And you're to be my sister, eventually, correct?"
Immediately Tina felt her face going red and she hurriedly tried to stop it. "I haven't- Newt-"
Theseus chuckled. "I'm only teasing." He looked at her and added in a lower voice, "Although you must know Newt fancies you."
Tina took a breath. Of course she knew by now. Newt had shown it. "Please don't take offense, Mr. Scamander, but I didn't think Newt would tell you."
"Oh, he hasn't," Theseus said matter-of-factly. "When I asked him to provide a solid reason for a lift on his traveling ban, he hinted there was a promise he'd made in America." Newt's brother shrugged. "I only connected the dots."
A promise. Tina remembered. How would you feel if I gave you your copy in person?
Theseus only smiled knowingly and stepped away, letting his little brother and his future sister speak together in private.
