Keras is shot in the chest with an arrow. Next time we see him his right arm is in a sling, and there's no sign of a chest wound.
While Major Sheppard and the team are looking at the status display, you can notice the landscape is having a hard time keeping up with the CGI.
Keras states that he is 24, and that tomorrow is the first day of his 25th year. However, the first day of your 25th year is the day you turn 24, not the day you turn 25. Similarly, he implies they live for 24 years, but when you turn 25, you have in fact already lived for 25 years.
The entire episode is one giant plot hole because the energy field that protects the children is the very reason the crew crashed in the first place. They cannot leave the children's village aboard their shuttle as long as that field is activated, yet the episode ends with the field reactivated and it is never explained how the crew is able to leave and get back to Atlantis.
Dr McKay parked the puddle jumper outside the energy field when he returned from testing the ZPM.

At 7 minutes, there is a white five-gallon bucket visible in the children's camp.
