(I've actually messed it up 3 separate ways
-this, which he doesn't do when he has his lisp but starts doing so after his death
-he starts alternating with a 0, not with o (ultimate wifeguy)
-his alternating continues between messages and don't 'reset" back to 0 if he used it last
and ofc i tossed the twos back in just for fun
forgive me sollux im doing my best orz )
