Michelangelo:
-Mikey tries to hide it from you for a while, mostly because he doesn't want you to be aware of his added abilities. He thinks it's just funny now when you try to plot an escape or fight back, since now you really have no chance. Most likely, you never even realized he was a vampire until he first sinks his fangs in your wrist.
-He thinks biting you is like, subtly romantic since you're more or less blessing him with your blood. You're allowing him to live off your own life, and it just pulls him further into his delusions of love. Obviously you'd fight back harder if you truly hated him. I mean, so far, he only has to chain you down!
-Mikey will constantly talk about your future with him. Now that he's going to live forever, he knows he actually means it when he says he's never leaving your side. He'll track down the original mutant to get them to infect you, ensuring that you'll be with him until the sun goes out. He's absolutely giddy at the thought, updating you every day on his hunt for the mutant until he finds them.
-Before he can infect you, he's even clingier than before. His skin always feels cold now, so he's drawn to your natural warmth and just likes to be near you.
-Watches you sleep a lot as he lays with you. Now that he can see in the dark, he doesn't want to waste a single moment where he could be admiring you.
-Once he finally turns you, he's ecstatic. His only grief is that he can't feed from you any more, but he's plenty happy with the certainty you'll never be able to leave him.
-If you complain about being turned, he'll get upset. He did this for you! He ensured both of you would be together forever more, and now you're being ungrateful. He'll pout for a while, trying to convince you of all the ways your life is better now.
-He'll withhold blood from you if you misbehave. Because you obviously can't hunt yourself, you rely on Mikey to get you your food. If he thinks you're being unfair, or aren't listening, he'll conveniently 'forget' to get enough food to feed you as well.
-He gets surprised when you fight back more after being turned, your enhanced strength and speed making him question his choice for a small while. He doesn't like that you have a better chance of leaving now. He obviously wins, but he's afraid he'll slip up and you'll get away. He keeps you chained tighter for a while, at least until you've calmed down. No matter how long that takes.

Donatello:
-He doesn't tell you of his new infection, but he doesn't hide it either. It's just another mutation to him, one that's more beneficial in a lot of ways once he realizes how much more he can do. He doesn't really see why he should tell you, especially when you're fighting him at every turn anyways. You'll probably find out after seeing him storing blood bags in the fridge in his lab, which causes you to freak out.
-Once you're aware he's a vampire, he'll start feeding off you more since he finds it more convenient than going out. He likes holding you and just sinking his teeth into your shoulder while he works. It keeps you both still and close, and it prevents him from having to find his own food. He claims the prolonged contact helps you both bond whenever you try to fight him.
-Donnie is obsessed with getting you infected as well. He's terrified of losing you somehow now that he knows he doesn't ever have to. He'll hunt down the original mutant to get you bit, not even telling you of his plan until you're already bit. He doesn't want to give you a chance to try something stupid before he's able to secure your place by his side, even if he knows he won't be able to feed on you anymore.
