What's up with Baldock? or, Marlowe in Performance

"My name is Baldock, and my gentry
I fetched from Oxford, not from heraldry."
(Edward II II.ii.242-43)

These lines seem to indicate that Baldock stems not from a warriors background, but from the University at Oxford. It comes in response to King Edward's questioning of his clan and to whom Baldock owes his allegiance. I think that such a response would signal to Edward II that Baldock does not necessarily descend formt eh conniving noblemen that have recently betrayed him, and thus is someone that Edward can trust. This is further supported by the fact that they were referred to Edward by his neice, who stated that they were servants of his brother, made slightly ironic by the fact that the Earl of Kent, Edward's other brother, recently betrayed him.
On a slightly seperate note, this Act started me thinking about the various different performance options that would be available from the text. It certainly seems to be rife with possibilities. One could, for instance, through visual cues, portray the noblemen and scheming and double-dealing, and thus the primary villians in the piece. The same could be said, however for Gaveston, who connives and manipulates Edward often. Yet it also seems to me that because of his various errors in judgement and inability to make a decent political gesture to try to calm the strife that surrounds him, that Edward is a fairly weak king, and deserves to be portrayed thusly. Additionally, the themes present seem remarkably before their time, the undertones homosexuality and homophobia could be excentuated in performance to make the play much more of a message piece. Having not read the end yet however, I'm not fully certain what the message would be.
