There is indeed - it seems madness that men would be so eager to risk their lives at the drop of a hat as it were. Poor old Aumerle has to fight Fitzwater, Percy and another lord, and Fitzwater has to fight Aumerle and Surrey. Chances of surviving all that would be pretty slim. Sounds crazy - and this was peacetime!
The other interesting side event in this short act is that this is where Bagot seems to escape the chop. Bushy and Green have already been despatched, but here Bagot has cleverly hinted that he has information about Gloucester's death, and this seems enough to distract Bolingbroke's attention from dealing with him.
At the end of the scene, after Richard has been deposed, Carlisle has a premonition of the violence that this act will lead to:
BISHOP OF CARLISLE
"The woe's to come; the children yet unborn.
Shall feel this day as sharp to them as thorn."
Richard was deposed in 1399 - the Wars of the Roses did not end until 1485.
