Last month Theo was having a lengthy discussion with Draco regarding their astrological compatibilities (which were apparently astronomical resulting in an incredibly dynamic friendship that were largely due to the implication that Theo – as an Aries – loves putting Draco's – as a Gemini - brilliant ideas into practice with the latter egging the former on to glory) and why it should be considered a weighty argument in why Draco shouldn't have had Karkaroff's messenger killed while Mercury was still retrograde.
