That is reasonable to assume.
However, we have seen sparks find accidental inspiration from various sources ( just look at all the varied things that distract Agatha).
If Othar attempts to kill a spark while in a biology lab, he very well may say: "Wait a mo'. Look at these equations left by Dr. Von Herpes! I've been going about this all wrong!"
The only hope is that he might not have the skill as Othar has been described as a bit...stupid.
