You grabbed him?
Lets imagine this for a moment.
You are less than a foot long, and every instinct in your being is telling you that anything larger than yourself is going to eat you. So from the sky comes this powerful five fingered hand and grabs you.
Under these circumstances wouldn't you be a fighting for your life to stay alive?
Remember extreme stress can kill a monitor or any herp.
Don't force your monitor to do anything.
Be patient, wait till your little guy gets a little size to him, and for now just interact with him calmly without trying to handle him. As your monitor gets older it will get bolder. Savs are generally pretty laid back, but in my experience in caring for a few, the juveniles are pretty skittish, they get over some of that with age. (Sometimes they don't).
BTW: I Thought you had a pair of Timors Monitors and weren't you trying to buy a Carpet Python not too long ago? How are those animals doing?
