The Titan who has feelings

Eren finds out about his brother

Petra, Oluo, Erd, Gunther, and Eren 3dmged their way through the forest bumping into Mikasa and Levi on the way back.

~On the Survey Corps Mess Hall~

"WE ARE NOT JOKING!" Eren yelled angrily at the whole Survey Corps who refused to belive the Levi Squad's story "What? You expect us to belive the titan with feelings exist?" Asked Jean "Eren, I know you miss father and I do to, But you need to stop this none-sence what father told us was a bedtime story, A fiction. There is no such thing as A titan with feelings" said Mikasa sternly "well Eren's titan has feelings" Said Hanji "Anger" Said Levi rolling his eyes "But-" Eren was cut off "Enough Yeager, I can't belive you even got the squad to do this idiocity with you" Said Levi "BUT HEICHOU! ITS TRUE" Petra said standing up for Eren "Is that so Petra? Then would you mind explaining how this titan looked?" Asked Hanji with a notebook and a pen "Hanji stop" Said Levi massaging his nose bridge "He wore a armor like Crystal around him that covered his whole body especially his weak spot! He even got a crystalized head gear!" Said Petra, Hanji nodding as she wrote about this new descovery of a Titan. Levi sighed and rolled his eyes "Alright enough of this bull shit, Yeager and Petra you are incharge of cleaning the stables" Said Levi "Yes Levi-Heichou" They both said in defeat "YES!" Screamed Jean in happiness "You too Kristein" Said Levi and Jean sulked as well.

"Eren..." Armin said as he stood up and went to the superior's desk where Eren and the other Levi Squad sat "Yes Armin?" Eren asked looking at Armin "H-Here" Armin handed Eren a brown envelope "Huh? What is this?" Eren asked "I-I don't know Grandpa gave it to me before he was sent to Wall Maria telling me to give it to you when the right time comes and I just thought that maybe today is the right time..." Said Armin "Huh? Where'd your grandpa get this?" Asked Eren "Well Grandpa told me that It was given to him by Dr.Yeager." Said Armin "Father?" Questioned Mikasa as she went to Eren's desk and stared at the envelope.

Eren opened the envelope and inside the envelope was 2 papers one was a birth certificate while the other was a letter

Birth Certificate:
Picture:
Name: (Y/N) (L/N) Yeager
Birthday: (Your Birthday)
Gender: Male
Parents:
Grisha Yeager (Father)
(Mother's name) (L/N)
The Letter:

Dear Eren
I know that you must be angry at this new descovery. Yes this is your brother, I had an affair with another person an innocent person who didn't know that I had a family and as a result your half brother is made. Your brother is the same age as you though you are younger/older. (Depending if yoyr birthday is earlier than Eren's then your older but if Eren's is earlier your younger)

Eren and Mikasa were shocked at the new descovery "A..Brother?" Asked Eren as he stared at the picture in the Birth certificate of his brother.

"Eren, we must find him" Mikasa said as she stared at her adoptive brother. Eren nodded his shocked face turning to a determined facide.
