Who would be the big spoon?
Eren would be the biggest of the spoons, holding onto Levi, whom in turn would be holding onto Lady Gaga. Let's be honest, now that Levi has his hands on the two people he cares about in his life he's not going to let either of them go.
They'd all wake up at a similar time due to Gaga's phone going off about the latest news scandal about the three of them. Eren would roll over and place a pillow over his head to block out the noise, while Levi would smirk slightly, knowing that the three of them were doing something right to be talked about on a regular basis.
Do they have nicknames for each other?
Levi uses 'The Queen' and 'The Brat' for them respectively. Gaga calls Eren 'Cutie' and Levi 'Shortie', both of which, hate her for. Eren doesn't really use nicknames for them, but that doesn't mean he doesn't care for them, he just thinks there is no point having so many names thrown between them.
What happened when they met each other’s parents?
Eren took them to his mother's grave, both Levi and Gaga sat beside it and talked for hours about how happy her son had made them. They decided not to meet his father for now. When meeting Gaga's parents, they asked her how long the fling was going to last and had no hope for it holding out very long. Levi's parents were... shocked to say the least. Mainly because Levi actually had a partner and somehow knew his idol. It took about an hour of explaining to them that they were in a poly-relationship and were happy like that.
How do they apologise after an argument?
If Gaga is upset; Levi is usually on his knees begging Gaga not to leave. Eren then joins him on his knees, but for another reason. Gaga likes to have control of her boys. However, if it is Eren, the two of them will kiss him and hold him close, apologising for everything the pair of them did. If Levi is upset they clean the entire house and don't bring it up again.
What would they be like as parents?
A fucking trainwreck, and that's putting it nicely. They would firstly be in the news for Levi getting Gaga pregnant, and yes it would be Levi's child. He wouldn't pass that up, and he rather likes to be be in the middle of their sexual interactions. They'd then have to take the child to Gaga's concerts and tours. Luckily Levi would still be employed due to him designing Gaga's outfit, but Eren would basically end up being the baby sitter for his non-biological child.
Well they all agree that it isn't Eren. Truthfully with the amount of money they make they very rarely cook for themselves.
Surprisingly it's Eren. Sure Gaga can give them anything that they've ever wanted, but it is Eren who makes sure that they're both stressfree at the end of the day and comforts them. He's the one who initiates the hand holding in front of the paparazzi and he's the one who speaks fondly of them in interviews.
What sort of gifts do they get for each other?
They don't really do gifts just because if they want anything Gaga will get it. No questions asked.
Who gets jealous easiest?
Eren, because he's seemed to always have this crush on Levi and he's worried Gaga will take him away completely. It's not true. Levi thinks that in that situation if one of them was missing it wouldn't work properly.
Who gets more excited for events e.g.. Birthdays, Christmas?
Gaga and Levi are too busy to remember these things, so Eren.
Who is the most adventurous?
You've seen the kinds of things Gaga wears right? She's the most adventurous, however they are all equally as adventurous as each other, Gaga only wins cause she does it publicly.
Who is the most protective?
Levi, he doesn't want to loose either of them. Not after how long it took for him to convince them it would work.
What would they have been like as childhood sweethearts?
Levi would have played kiss chase with them and then aimed for the pair of them, dragged them behind a tree and kissed them both before blushing and running away. Eren and Gaga would then both approach him at the same time and kiss each cheek saying they liked him too.
