Now some may view that as inappropriate, and yes, it is. But Twi was also enjoying it, hence why she didn't stop him right away. Interesting descriptions.

Very clever comic idea. I've never seen this done before. Watching Spike's expressions including Twi's as he is doing this is great. I love Spike's final face in the last panel. He is truly horrified.
Thankfully, it seems things never last with them for long, so by the next comic, everything will be A-okay!
