Deciphering the meaning of tihs language

A quote that really stuck out in my mind while reading was in Act 2 Scene 3 Line 170-174 in which Maria says, " Sport royal, I warrant you. I know my physic will work with him. I will plant you two, and let the Fool make a third, where he shall find the letter. Observe the construction of it. For this night, to bed, and dream on the event. Farewell."

This quote as you may recall was done as a free write in class and I felt the need to talk about it further and put more thought into it. We went over want we thought sport royal meant and I from the other information given to use in and around this excerpt only can only connect it with the form of hunting as was done during these times where royalty would go out and corner and trap their prey. Maria is planning on trapping and trying to making Malvolio look like a for lack of a better terms a "fool". She is going to try and destroy him and in order to do so she is going to use Sir Toby and Sir Andrew to make her plan fall into place and also use the Fool as a third party and make her plan really meaningful and make sure that Malvolio is humiliated. She seems to have an intricate plan which she is starting to put into the works but before she really gives to much she departs and this allows you to see that Malvolio is the hunted and Maria, Sir Toby, and Sir Andrew are the hunters trying to corner, capture, and kill Malvolio. The fool i think is just a scapegoat who will be used to make the plan stronger.
