the most passive-aggressive medic possible. if this were an MMO, he'd be the friend-of-a-friend healer that one of the DPS vouches for to call in when one of their main healers has to go to their daughter's ballet recital on the night of the guild's schedule raid run, that fusses and whines at the tank for taking damage (you know, the thing they're supposed to do) but unfortunately is good enough at keeping people alive that he isn't kicked from the group. yeah, he'll bring the lead the herbs, but he's not gonna be happy about it. and yeah, he'll slap an open wound salve on you or dump a flea remedy in your fur or pick ticks off your ears, but he's gonna bitch the entire time about how nasty you are and how you need to take a bath.
honestly he'd rather be laying in the sun doing nothing, but he's the herbalist you need, not the herbalist you want so might as well buck up and deal with it.
