Quote 1
"We're his army," said Neville. "Dumbledore's Army. We were all in it together, we've been keeping it going while you three have been off on your own –."
"It hasn't exactly been a picnic, mate," said Ron.
"I never said it had, but I don't see why you don't trust us. Everyone in this room's been fighting and they've been driven in here because the Carrows were hunting them down. Everyone in here's proven they're loyal to Dumbledore – loyal to you." (29.34)
Faithful Neville stands up to Harry a bit here, reminding him that he's not alone – everyone in the DA has proven their mettle, and they've just been holding down the fort until Harry returned.
