It's not often that the Jims are given a job that only they can do.
Usually their 'job' is to keep out of everyone else's way, and though they don't always manage it, they are more than willing to give it a go. So you can imagine their confusion when Google comes to them and tells them there's something he needs them, specifically them, to do. Apparently it's the Host's idea, though Google doesn't go into it in much detail, simply bringing them to the clinic and pushing open the door to Bing's room.
Jim reaches for his brother, nervous. They've still not been allowed in and though they've been told Bing's improving, their journalistic nature means they trust nothing they haven't seen for themselves. As they walk in, they see the cyborg sat at the end of the bed, and watch as he pales at the sight of them, his face falling and looking like he's seen a ghost. That's not the reaction of an okay person and they both stop in place.
Other Jim gives a small wave, noticing that Bing's apparently missing an arm and he wants to ask, but Google shoots them a look that says, 'do so and I'm throwing your camera into a ravine'.
The aim, it would seem, is to test the leg, helping Bing to walk to the garden where King is waiting after Google apparently kicked him out. Having only one arm, Bing can't exactly use crutches, and the Jims are about the same height, they're surprisingly agile, and are able to do things in sync without having to really think about it. That and they no doubt are getting annoyed at being kept out of the loop.
Bing won't stop staring and the Jims stare back, unsure if they've done something wrong or if Bing just hates them, so they don't hear Google the first time he asks them to go stand on either side of the cyborg. When they do hear, they move and notice that Bing won't look at them. The two of them share a look over Bing's head.
There's a couple of rules to this job. If Bing starts to fall, they have to catch him, they can't run or be too energetic, let Bing set the pace, and if he stops, they stop. Fairly simple.
The pair of them help Bing to his feet which he's a bit unsteady on, almost falling back down, but they have him and he's soon steady on his feet.
"How does it feel?" Google asks.
The cyborg glances between the Jims, his cheeks slightly flushed as he looks uncomfortable. "Weird."
"Good weird or bad weird?" Jim asks, from Bing's left.
The cyborg doesn't offer an answer and the Jims are almost certain they've done something to upset him at this point, so they remain silent as they continue to make their way out. Google is following a short way behind, watching them with a curious frown.
