Lougosi Bromance

Arguably Louis left the shishigumi to avenge Tem more than to help Legosi... supporting Legosi was just the means to accomplish this goal, just like giving Legosi his leg was a means to 'rid himself of his curse'. Louis only thinks about Legosi when he feels his stump ache, or when he hears about something involving him on the news. He makes his own plans without thinking to include Legosi, and only works with him because he shows up in the same place at the same time - eg. in the kopi luwak investigation and the current recon of the back alley market. Legosi thinks of Louis more often than vice-versa and does regard him as his friend, but Legosi has lots of friends and cares about them all... he worries about Louis slightly more only because Louis is a herbivore, and tends to get involved in some dangerous groups and activities.
