I think Newt would have found a creature with the ability to time travel forward. Don't imagine Newt discovering this by accident and ending up about 70 years in the future, and meeting Luna Lovegood when she's about his age. Don't imagine them falling on love. Don't imagine their first kiss, after Newt shows Luna all the creatures he takes card of and she realizes how much she loves him. Don't imagine their wedding, officiated by Pickett. Don't imagine their kids. Don't imagine them teaching care of magical creatures together after Hagrid retires. Don't imagine their kids being sorted into Hufflepuff, just like their father. Don't imagine Newt and Luna living together and taking care of all Newt's creatures. Don't imagine their kids begging to take over. Don't imagine Luna and Newt teaching first years to tickle a niffler. Don't imagine them leaving behind a lasting legacy of love and acceptance towards all creatures. Don't imagine their, story being told at Hogwarts even hundreds of years later. Don't imagine Newt Scamander and Luna Lovegood falling in love.
