If the readers already love him, it will be important to have a plausible reason for why he's not around at the moment (Law shows set in New York seem to have the meme that someone is "in London" - a trick they apply with varying levels of plausibility). Other characters might mention his absence, and when he comes back, readers will also want to know what he's been doing. It's OK. (With the usual Writers caveat of If It's Done Well).
