i'd actually really like that? rose is apparently the one everyone is going to for romantic advice which is kind of adorable because rose is not a romantic person at all
rose mentioned davekat to mikleo offhandedly (before talking to karkat) when they were talking about ~interspecies relationships but it wasn't anything mikleo particularly followed up on/asked about at all
oh yeah ot but seth i'm dying curiosity, when mikleo and rose were talking what was he going to say to her after "you..." had he not drunkenly passed out
