You may (or may not) remember our joint exclusive sneak preview with Sonic Stadium and Sonic Wrecks of Sonic Colors’ new voice actors a while back. In that clip, Tails mentioned only he can read what his translator says because it’s in Binary.
Those sneaky writers took advantage of that and snuck in a nice little message to those intrepid enough to catch a glimpse of Tails’ PDA.
Slight and minor ending scene spoiler, so view at your own discretion.
