When they heard that Vega would accompany Tatiana to interview the SpaceLab director, Altair and Mischa knew that it was time. Vega would soon meet Ren.
Last year, before Vega took the memory potion and got her memory removed for the past 6 years, she wanted to be fair to Ren, who begged her for a second chance.
The Lindens were angry and didn't agree if Ren was given a second chance after Vega forgave his actions. However, Vega was adamant about her decisions.
Vega's reasoning was, Ren committed all his crimes to take revenge on her father's actions that resulted in Friedrich's deaths and thousands of other victims. Without Elios killing Ren's father, the man wouldn't have turned out to be who he was now.
He was raised in hatred all his life and didn't know otherwise. If his parents were still alive, he might have been a completely different person.
