For anybody who missed this adorable NPC.
The first two screens happen sequentially, BEFORE the end of the game..
The third is from THE EPILOGUE. Don’t know if you had to have talked to the lion before that point to see this, but I assume you had to have spared mettaton (I’m missing a screen directly before #3 where he basically just says he wrote a fan-letter to Mettaton). Look how happy he looks!
Also, Mettaton confirmed for being as SWEET and GENEROUS as he is glamorous. (And here I spent the whole game thinking he was just a self-obsessed egomaniac..)
