He spends the time between two thoughts: keeping Jyn safe in his arms and doing his best not to jostle her, and all the steps he needs to take to get them all into that basement before the creatures reach them. He can't do anything for Espi and Mateo until Jyn and the baby are safe first. Cassian had no real family growing up. Jyn became his family, became the most important person in his life. Now there are several most important someones, in a family with a wife and children he never dreamed possible. And while he's always known he'd do anything for them, he never expected it to be put to such a very real life or death test.

He can hear the creatures in the distance, and he breaks into a jog. It might be too much on Jyn, but better a little more pain than no pain because they've been killed. The blankets muffle the baby, but it's not perfect; he can hear it, which means so can they. He might be moving faster to outrun the creatures, but it's not a very soothing pace for the infant who's already also dealing with hunger. There's another screech and Cassian hurries along even faster, the barn so close yet so far.

One of the aliens bursts out of the corn just as he skids into the barn. He kicks over the mattress and climbs down the ladder with them in his arms. He hurries Jyn to her feet, knowing full well she might not be able to stand, but he has to get the mattress sealed back over the hatchway. He yanks it just as the creature comes barreling into the barn, and he slides the trapdoor shut too, bolting it.

It thrashes above them, but the room has been built to keep any of their sounds from traveling out. At least that was the goal. It's never been tested so earnestly. Once the top door is secure, he hurries over to Jyn where she's struggling with the baby box.
