I believe certainly that this baby was an accident though that did not make it any less loved by both of its parents when the time came. Parents who were,after
all,in love. Lupin did not want the child and was maybe ashamed of his lapse of judgment in forgetting protection and annoyed that Tonks was so happy about it
when he had so many misgivings. In many ways he was using fears for its safety as an excuse and wanted to escape until Harry sorted his head out the hard way.
