Nate hates to trample over their tender reunion but the guardsman are still coming. Rodeo may have taken out a few but the flock is rearing to trample. They've already gone through the door with the busted lock. Many of them have taken cover and stray bullets spray whenever one of the bad guys takes a chance shooting at the Woman, her baby, the brother and the man that let them inside.
"We best tae be goin'" he yells over to them, himself trying his best to keep them covered, shooting at whatever flashes of gunpowder he sees when any of their pursuers fire. There's only one way for them all to go, luckily this has been planned well in advance and Nate has taken precautionary measures that would allow for them to slip out the other side. He's sure if they don't hurry they could be cut off and that would make for a helluva unrighteous ending to this bust-out.
Giving Addie, the baby and her brother a head start he yells out, "Go...I'll be behind ye."
