Got eviction summons, was not even aware I was past due! Advice?

So, I wake up today to a court summons for eviction. The summons states that a pay or vacate notice was served on 4/11, but I was home that weekend and received no notice.
Last month I was in and out of the state the whole month dealing with some family stuff, and my 19 year old brother stayed at my place to "help out." I wrote a check for rent and asked my brother to bring it down to the office on the 1st. The exact amount of rent was taken out of my bank account.
After making some phone calls, I'm certain that my brother used my check book and wrote himself a check in the same amount rather than paying my rent. So on top of being evicted, my brother stole almost a grand from me. What a start to a day...

Is there anything that can be done at this point to stop the eviction? Can I speak with my landlord, or is that not allowed since they have filed a lawsuit against me? I was already intending to move out at the end of this month, but I do not want an eviction against me. Also may be worth noting, my kitchen has been without water due to a leak for 2 weeks. They won't fix it, which will make it difficult to wash dishes to pack.....
