Everyone's at it on the Street tonight, and by it we mean each others' throats. Maria can't understand why Marcus didn't tell her the truth about that wedding invite, Karl wants Dev to stop asking questions about the fire that killed his missus, and Carla gets the opportunity to leave her brother high and dry. Will she have the guts to drop him in it though? Meanwhile Izzy's in a right panic down at the hospital because baby Jake's been diagnosed with a bowel infection, but is that really all that's wrong with the little lad? Better call Tina...
