Macha Doyle

Macha Doyle is one of the colonists at Zhu's Hope on Feros. She is busy working on the colony's water shortage after the geth attack, and can give Commander Shepard the Feros: Water Restoration assignment.

Doyle, like the other colonists, is dismissive of Shepard's questions and keeps asking the commander to ask Fai Dan about the colony. She appears to be much busier than the others and won't even turn to look at Shepard while she works. Doyle asks the commander to turn on the water valves down in the tunnels - the Normandy can't ship in enough water to supply them.

Shepard can ask, if Doyle knows what the problem is and how to fix it, why she hasn't done anything about it herself (a question that no one ever seems to ask NPCs). Doyle struggles to answer, saying she's hurting since the last geth attack and focusing on the water shortage makes the pain go away: whenever she tries to do anything else she feels worse. As she is infected with spores, the Thorian may have given Doyle a 'standing order' to get water flowing again. Either the Thorian knows how essential water is to human well-being or, as a plant, the Thorian is short of water itself and needs Doyle to get it. If Shepard helps get the water back, the grateful Doyle can hand over a reward.

Along with the other colonists, Doyle fights to defend the Thorian when Shepard returns from the ExoGeni Corporation building. She can either be killed or knocked out harmlessly with one of the gas grenades.
