I'm sure they're more than capable to take care of themselves, Ratchet now that they know that you won't be happy if anything happens to them. [He says that so both Bulk and Wheeljack can see it. If you get hurt not only Ratchet will scowl you two, silly Wreckers.]

Some fresh air and a bit of exercise would be good for Bulk's health too, it will get his engine running properly again.
