Regret is the second chapter of Swap on Titan and the last chapter of the Invasion arc.
Jared Lyon †
Lionel Hathaway †
Two unnamed gang members †
Jared had the gun pointed at Carla. He was grinning his head off and so was Lionel. He pulled the trigger. For Eren, it seemed like the world had slowed down. Lionel dropped Eren's mother's limp, headless body. The four gang members started running from the police who were right around the corner. Eren started hitting Hannes back.
"Why didn't you save her!?!" He yelled, angrily.
"Eren, when someone points a gun at you, all your courage will drain faster than water in a colander." Hannes said, putting the two down.
"What are we going to do now?" Mikasa asked.
"We could stay with Armin." Eren suggested, calming down.
The two left Hannes and went over to Armin's place. Eren was still shocked at what had happened.
"Oh hey you two." Armin said. "What's the matter? Are you alright?"
"A gang entered our home and shot our mother." Mikasa said.
"Oh dear! What are you going to do?"
"We were thinking of staying with you for a bit. Until dad gets back." Eren said.
"I'll have to ask my grandfather. Hang on a minute." Armin disappeared into the house. He appeared a few minutes later. "He said yes."
Eren and Mikasa entered the Arlert household.
A little while later, the trio were talking about the incident.
"Maybe they were after your father?" Armin asked.
"Maybe...." Eren said. "I'm definitely joining a street gang now."
"Me too," Mikasa said.
"And me." Armin said.
A year later.... Edit
The trio stood next to a dumpster in a dark alleyway.
"When's it supposed to start?" Eren asked.
"Right now." Armin said.
A hooded figure started walking towards them. When he got to them, he stuck out his hand.
"Follow me, kids." The deep voice said.
They followed the hooded figure to a warehouse where there were other children around the same age.
"Welcome to your initiation. Your instructor will be here shortly." The figure said. "Try not to kill each other while waiting." He cackled and left the warehouse.
