Mags knows her kids are ready; that she's trained them to the best of her ability. That's why it's that much harder when she watches them make fatal mistakes, has to face the families who put their faith in her, and it all culminates into crying in Manannan's arms year after year, tears staining the tribute pictures until she gets up to teach the next batch.
Bovina never holds high expectations. She'll teach them, fight for them, and ultimately end up carting the bodies back on the train, dealing with the silence in the car after the escort has passed out from alcohol. The Anasazi are ready to comfort her when she gets back, but she always refuses. She's not the one who needs support- the families do.
Woof is always hopeful. He's seen enough Hunger Games to know that upsets do happen, and he wishes so desperately for one of his, just one, to make it back. When Cora, and Cecelia, and Cotton make it back he is deliriously joyful for a while- and then he remembers his mentees who had to die for them to come back.
Silk is excited the first time she mentors. She's won the Hunger Games, she teaches at the DAEYD, surely her mentee will make it back. Luxe's warnings don't even make a dent in her mood; Silk is confident in her teaching abilities, in her shadowing of Platinum the past two years, and most of all in her tribute. When Emerald goes down at the Cornucopia, head crushed by the massive boy from Ten, she stares in shock. Then she starts to scream, and Luxe quickly carries her out before she starts tearing her hair out again.
Vera remembers all of them. Every time a Seven girl falls, she sits in her room and watches the interviews, training, and finally their death. Then, she watches her own Games. Vera O'Rourke loses herself in her mentees, taking on an attribute, a habit, a characteristic of theirs so that she doesn't have to be the girl in the recording.
Gates blames himself. He knows that his victory is the reason District 3 never wins, and he knows that his tributes will have no chance as soon as they step into that arena. He fills them in, in hushed tones, and what they choose to do with that information is their choice. He's proud of them either way.
Boudicca takes no pleasure in mentoring the Games. She knows it's for the best, that it's for the Capitol, but her tributes are usually about as ready as they can possibly be. All she has to do is use the sponsor money, stand back, and let them do what they need to do. If they fall, she makes sure they are given the highest honors at the funeral and never forgotten. They fell in service of the Capitol; what higher honor is there?
Granyte almost never mentors, most of Boudicca's proteges never spare the crippled Victor a glance. When Barty and Lyme make it back, then they listen.
Manannan pushes his tributes hard. That's why, when Thisbe made her first public appearance, Capitolites were surprised to see him letting the girl grip his hand like a child. That was the first indicator that the rumors about the 21st Victor were true.
Wren plants her seeds for each of her tributes and buries it in District 11, but one day Peacekeepers decide to do target practice near her mansion, and the little garden is destroyed. She knows she can't do anything about the Peacekeepers themselves, but she builds a little fence around her garden, replants the seeds, and vows to do something someday. It's the least she can do.
