[Even if Keith and the others had mentioned that Allura was also here, this was his first time seeing her. And even though from his perspective it hadn't been that long he still carelessly pops out of his fort, sending a few pillows flying.]

Allura! Hey! I didn't realize that was you. It's not easy seeing through that blanket.

[He looks down at the "Damage" he just caused his own fort. He picks up a pillow, sheepishly.]

They told me you were here, I didn't realize you'd been checking out the forts.
