The only thing holding Mirai Trunks back was the fact that she was accompanied by Krillin.
"Uh, Hi Trunks!" Krillin said. 18 just looked at Mirai Trunks coolly, the complete opposite of Mirai Trunks' white hot rage. His ki flared. He seemed only a hair from transforming into a Super Saiyan.
"What is she doing here?" he managed to say through clenched teeth. His voice shook. But what he really meant was: 'why is she still alive?' She and Android 17 had done nothing but terrorize the people in his time and this one. The only thing they deserved was death. But this android stood before him as if she was a friend of the Fighters. And they seemed completely at ease with her around! Bulma laid a hand on his shoulder.
"It's okay Trunks." She murmured soothingly.
"How can it be okay!" he growled and tore his eyes from that all-too-familiar face that was burned into his mind by hate and grief. He would—no could never forget their cold, ice-blue eyes, or their terrible joy of hunting him down and beating him to within an inch of his life. He looked at his mother and Bulma almost drew back at the look in Mirai Trunks' eyes. She could all but feel the heat of his rage. Gohan looked worriedly at 18 then Mirai Trunks, not knowing what to do. Vegeta had his sneer on and Chibi Trunks and Goten had no clue what was going on. They had been kept in the dark about 18's origin and Mirai Trunks' appearance. Chibi Trunks would have had a lot to live up to if he knew about Mirai Trunks. Piccolo was anticipating a fight to break out. Krillin's eyes darted from Mirai Trunks to 18 and back again.
"What's going on?" Videl whispered. She didn't have any idea of what was happening either. "Gohan!"
"Long story. I'll tell you later." He said quickly and walked up to Mirai Trunks who still had his eyes on Bulma. But despite his doubts of what Bulma had told him, he seemed to be calming down. Well, at least his ki had dropped slightly. "Trunks, it really is okay." He told his friend. Mirai Trunks turned his eyes to Gohan and his rage quieted a bit.
"Yeah," Krillin jumped in. "She hasn't done anything bad since you last saw her. I would know. We're married." Mirai Trunks' rage turned instantly to shock as he quickly looked up at Krillin. "We even have a daughter." Almost everyone smiled in amusement as Mirai Trunks' expression openly changed quickly from surprise to horror to disgust and then finally to wonder. Gohan sighed and relaxed muscles that he hadn't even realized where tensed. Mirai Trunks' ki had dropped back down to the normal level.
