It was a wet, stormy night in London, as Newt was awoken by Bunty, making him anxious saying that Frank had flown off making the brunette haired male worry, thinking something had happened, or the male thunderbird had sensed something was wrong.
He was telling her to stay with the beasts including the baby Niffler's because they or Nigel would ignite chaos so was getting ready to go, hoping he did not have to use memory charms, if any Muggles saw Frank flying around in the stormy skies, since thunderbird's could create storms.
Why would he fly away, and in tne middle of a storm?
He was using his beast tracking skills to find said male thunderbird near an nest, making the male magizoologist was surprised by, approaching, hoping that Frank was alright, realising what was in those eggs.
"Sorty for flying off Newton, but these thunderbird eggs needed me, as it's mother disappeared." Frank said, making Newt get it, that Frank had sensed these eggs were in trouble, like when tne obscuras had nearly trashed New York deciding to take the nest back to the apartment which Frank liked the sound of.
"Aww, so Frank was protecting an nest of thunderbird eggs, Newt?" Bunty asked.
"Yes, Frank is very protective of his kind, Bunty." Newt replied to her.
He saw Frank sitting on the nest of thunderbird eggs, as they needed warmth to incubate, not caring if certain beasts made fun of him sitting on an nest, because the mother had left, which made Newt worried so at least, the eggs had Frank to be there for them which Bunty thought cute, seeing Newt agree.
"I'm going to be alright, Newt, go sleep, besides I'm just going to be sitting on this nest." Frank told him, seeing him go to bed plus was being protective of the eggs, which Bunty got, leaving the male thunderbird be.
"Don't worry little ones, I've got you and sorry your mother disappeared, but daddy along with uncle Newt are going to take care of you, plus you have a sister named Tina, besides your cousin, Bolt." he told the eggs which was making him smile, despite it almost being sunrise.
The other beasts were surprised, seeing Frank sitting on an nest, plus Nigel was grinning mischievously, despite Albus warning the Niffler male to leave Frank alone, because the male was taking care of thunderbird eggs, so he would be cranky and tired from looking after the eggs so was hoping that Newt would help.
