This happened when Reno & Rude were running away since Bahamut was firing the blue thing at the big center like thing Yazoo & Loz were supposed to pull. -- FEH, I suck at describing. xD; So anyway..
Reno: What's happening behind us?
Rude: I don't want to look at it. *looks back*
Or at least... that's what the subtitles said. o_o| Funniest & most ironic thing ever. xD;
