I haven't seen this, but it sounds like Gundam Wing to me. Crash, shot goes off and bits of the building are falling on Relena - next thing you know Heero has the arm of his Gundam over her, sheltering her and is confused out of his mind as to how and why he reacted like that (since he wanted to kill her). Just from the description, it sounds very similar.Toxic Shade wrote:As for the 'arm reaching' reference, I believe they put that in their as to show that Ayato barely even knows what he's doing when he pilots it. He looks rather surprised to see that he saved her.
Maybe it's one of those 'cliche' scenes found in many anime. Or Eva is the only anime allowed to use typical scenarios and shots done for the purpose of conveying general ideas to the viewers.
