@Timowoof No, I just checked the raw. It says "もう7 8年前". The massive space between the 7 and the 8 means he's saying "seven", then saying "eight", not saying "seventy eight". He's saying "it was 7 or 8 years ago." 78 years obviously doesn't make sense, since Levi isn't over 78 years old and he's talking about an event that happened when she was younger.
