Terry was never one for people, they were all ants to him. Growing up dependent on the Guardians who shunned him to stay alive and attacked by the HalfBlood's that claimed to accept all, he felt out of place but at the same time better than them all. If they wouldn't accept him, if they wouldn't love him, then he must be better. Superior powers, superior mind, the only downside was his weak body. Living and working at Lake Forest Hospital, he became used to their glares, and he glared right back. 

However, when Alexandra showed up in his home, he knew things were going to go wrong very quickly, and not even he could stop the wreckage of a taboo break. However, he was a man of pride, his doctor's oath would not be broken to prevent the backlash of what was done.
