Howling:Assimilation2 questions (SPOILERS)

Okay, I have two questions regarding this series:

1) How are the Doctor and his companions able to enter the Star Trek Universe? It was established fairly early on in the new series that after the Time War, travel to other universes became nigh impossible.

2) In the most recent issues, the Cybermen suddenly turn on the Borg and are now apparently on the verge of defeating their former allies. This just doesn't seem right to me. The Cybermen are powerful, but I never thought they were anything near as strong and dangerous as the Borg. 82.20.113.152talk to me 09:47, September 28, 2012 (UTC)
