Christmas Intermission is a single strip inserted into the TF Busters #1 story arc in EGS:NP. It is listed separately on the main dropdown and on the archive page. However, since it is preceded and followed by the same story arc it doesn't count as a separate story arc (for counting purposes) but as part of the fourteenth one. It consists of the EGS:NP Comic for 2009-12-24 featuring Ellen and Nanase snuggling on sofa. (Also Brownie).
