Dirk does glance up at him when their hands make contact, but his frown has mostly lapsed, transforming his expression into a more severe version of its natural deadpan; it's pretty obvious he has objections, and he's about to voice them when Emet rephrases it as a request, a favour and caps it off with a fucking kiss.

Which is effective at shocking Dirk into bewildered, flustered silence.

There's a second or two of lag before he recovers enough to turn his head away, which does less for hiding his reaction (it's far too late) than it does for communicating the depth of his unwillingness to concede on this. It does, however, make him look a bit like he's staring at his offending leg with cold disapproval.

"I don't want to hobble around like a fucking cripple for weeks."
