Olena Shkrum, Savchenko's colleague in the Batkivshchyna faction, was among those who were meeting her at the airport as the pilot had been brought home in a largely unexpected move, Ukraine Today reported.

"She feels that she has missed two years, and she actually feels really bad about it. She is trying to fight the system very hard right now," said Shkrum as Nadia Savchenko on Tuesday finally made her first appearance in the Ukrainian Parliament.

"I think she will change a little bit some of the questions that we are used to, which we are frustrated about. She will just push us to do it," Shkrum said.

It was quite hard to see her seat all the time, [see] that she is absent, and you know that she is in prison. Because [her seat] is right in front of me. And you feel very much responsible that she is not here with us. [...] So obviously we are very much relieved, although we have to fight for all the other people who are not MPs who are still there in Russia, and there are a lot of them," said the MP.
